Ignition System Chugging

my truck did that while i was driving on freeway then would backfire i had changed spark plugs and wires and when i did that it made my ignition coil stop working but i just cleaned it off when i dies while driving just throw it in neutral and restart it so you dont have to come to a stop

From your owners manual, the shutoff is not a manual button:
Roadside Emergencies
FUEL SHUTOFF
WARNING: If your vehicle has been involved in a crash, have the fuel system checked. Failure to follow this instruction could result in fire, personal injury or *****.
In the event of a moderate to severe collision, this vehicle includes a fuel pump shutoff feature that stops the flow of fuel to the engine. Not every impact will cause a shutoff.
Should your vehicle shut off after a collision, you may restart your vehicle. For vehicles equipped with a key system:

1. Switch off the ignition.
2. Switch to start position.
3. Switch off the ignition.
4. Switch on the ignition to re-enable the fuel pump.

For vehicles equipped with a push button start system:

1. Press the START/STOP button to switch off the ignition.
2. Press the brake pedal and press the START/STOP button to switch on the ignition.
3. Remove your foot from the brake pedal and press the START/STOP button to switch off the ignition.
4. You can either attempt to start the engine by pressing the brake pedal and the START/STOP button, or switch on the ignition only by pressing the START/STOP button without pressing the brake pedal. Both ways re-enable the fuel system.

Note: When you try to restart your vehicle after a fuel shutoff, the vehicle makes sure that various systems are safe to restart.Once your vehicle determines that the systems are safe, then the vehicle will allow you to restart.
Note: In the event that your vehicle does not restart after your third attempt, contact an authorized dealer. 2015 Edge Owner's Manual

code p 0720 refers to output shaft speed sensor (OSS)---circuit malfunction===causes ---wiring --- OSS sensor--- ECM---TCM
as the OSS reports shaft speeds to the TCM so that he correct ratio can be selected, I would be having it tested / replaced

It almost sounds as if the vehicles theft deterrent system is shutting down. Is your vehicle equipped with a theft deterrent system ? If so there's several things that could be wrong or it could be as simple as doing what's called a relearn for that system. Attempt to restart it, once it starts then dies leave the ignition switch in the run position, if equipped with a theft system ( check your owners manual) there will be a light in the instrument panel that will begin flashing , while leaving the ignition switch in the run position wait for about 10 minutes, the light SHOULD stop flashing. Turn the ignition switch to the off position and attempt to start it. If it still bothers you're either dealing with something deeper or different type of a problem. Good luck.

Yes, I think I can help you. Isolating which system is causing the problem is the SECOND step in ANY automotive diagnosis. (you might want to remember this for future reference - it can make your life a whole lot easier) The FIRST step is to "verify the customer complaint". Since you ARE the customer, then you have already verified that the engine keeps dying, so that makes "isolating the sytem" the FIRST step in your case. This is where your problem lies.

You are replacing parts trying to fix the WRONG system..that is why it is still dying. The problem is the IGNITION system NOT the FUEL system.

With all that said, your ignition system is shutting down. The MOST LIKELY cause is a bad distributor pick-up coil. It is located in the distributor under the distributor cap and looks like the picture below.

Given this limited amount of information, my first thought is that your transmissions lock-up torque converter is not releasing.

It is an automatic transmission.......correct?

I need to know if the engine flat out dies as your vehicle stops... or does it spit and sputter... then die slowly????

If it dies very quickly just as your car is coming to rest:
There is a solenoid (electriclly actuated) valve inside the tranny pan. It is usually servicable without removing the transmission. It locks up your converter under certain conditions; and should release it when you apply the brakes and/or slow down.

If the lockup converter fails to release as you come to a stop, your engine will die abruptly.
This is either a malfunction of the lock-up solenoid or valve; or it could be a wiring issue.

VERY IMPORTANT: When restarted immediately after a stall, does it idle in gear smoothly?????

Is your "Service Engine Soon" light on?

Now if it is a slowwwww death, and does not idle smoothly immediately after a stall:
Then it is probably not related to your transmission at all; but rather the engine itself.

Areas to consider are :The fuel system (fuel pump, injectors, pressure regulator) vacuum hoses, ignition system (bad spark plugs, failed plug wires, weak ignition coils), or the emissions system (sensors etc).
Also, there is an IAC motor that controls the engine speed at idle.

That will require more data from you if possible.

Good Luck!!

is it a stick immobiliser?
If your vehicle does not start and the LED continues to flash while the Ignition is 'ON', this means that the Immobiliser system has not recognised the transponder stick.
Simply turn the Ignition 'OFF' then back 'ON' again. If the Status LED continues to flash, move the transponder stick closer to the key barrel until the LED stops flashing and turns 'OFF'.
If the transponder stick on the key ring does not disarm the immobiliser or the
transponder stick is misplaced, you can override the system by entering a 5-digit override number. Each vehicle has a unique 5-digit override number. This number is recorded on the
customer’s owner’s manual. If the customer loses their owner’s manual / override number, the number can be found by locating the vehicle’s Daewoo Stock Number (D.S.N). The customers override number is the last 5 digits of their D.S.N.

Overriding the system using the example 5 digit code 2,1,0,6,2
Important Note: 10 flashes of the Status LED represent the number ‘0’.
1. Remove the Transponder from the Key Ring.
2. With the system armed (LED flashing slowly) Turn the ignition ON/OFF 5 times, with the final position being off.
3. The LED will turn solid red for 2 seconds and then begin to flash.
4. When the LED flashes twice (2), turn the ignition ON. (number 2 was entered)
5. Turn the ignition OFF and wait for the LED to flash once (1) and then turn the ignition ON. (number 1 was entered)
6. Turn the ignition OFF and wait for the LED to flash ten (10) times and then turn the ignition ON. (number 0 was entered)
7. Turn the ignition OFF and wait for the LED to flash six (6) times and then turn the ignition ON. (number 6 was entered)
8. Turn the ignition OFF and wait for the LED to twice (2) and then turn the ignition ON.(number 2 was entered) The LED will turn solid red, which means the system is now overridden and the vehicle can be started. If an incorrect number is entered in, wait 11 flashes then start the procedure again.
NOTE: This is a one-event override. Once the ignition is turned off, the vehicle will passively immobilise after 30 seconds. If your 5 digit override number does not override the system, the chances are that you entered the wrong number. If this is the case, you’ll need to re-enter the override number
and try it again.

the security system resets itself after about 15 minutes. If it was the security system, the car would not crank over. Why do you think it's the security system?
do you have gas in tank?

Is it a Ford security system, with the flashing light on the dash?


Principles of Operation
The PATS uses a specially encoded ignition key, this key is not compatible with previous vehicles or any current model year vehicles. Each specially encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique encrypted identification code out of over 18 billion, billion combinations.
Each encoded ignition key must be programmed into the vehicle's powertrain control module (PCM) before it can be used to start the engine. There are special diagnostic repair procedures outlined in this manual that must be carried out if a new encoded ignition key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to their vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to Key Programming—Unlimited Key Mode in this section.
The PATS transceiver module communicates with the encoded ignition key. The module is located behind the steering wheel column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the encoded ignition key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The PATS will be activated and will disable the vehicle from starting if there is a:

• improper encoded ignition key (example — Taurus/Sable key).
• damaged encoded ignition key.
• unprogrammed key.
• non-encoded key (key has no electronics).
• damaged wiring.
• damaged transceiver.

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
