Engine the engine dies every time i come to a stop the engine also idles up and down but stops

fuel filter,coils module.

MAYBE CHECK (MAF) MASS AIR FLOW SENSOR

Pull the MAF sensor and give it a cleaning the correct way.Sometimes something shorts those probes(tiny wires and delicate) and your engine will cut a shine on you.
Look up how to clean the MAF sensor if you don't know how. don-ohio

your idle air control valve is going out located behind the throttle body.

it is either the idle control valve or the egr valve sticking.just say that you have just come off of the interstate and had to stop suddenly,if the engine starts acting like it is going to die or just dies it is most likely the egr valve. good luck let me know if i can help in any other way

if u see check engine light then there is a fault, probably idle solenoid ,wiring , ECU

The mechanic should check on the idle .Because the Idle of the truck is adjusting by it self . That causes the truck to stop .check the Idle then lock it up to so that it will not adjust until it will make the truck stop .the main reason why the truck stop and pressure guage going down steadily is that no fuel enters the fuel pump when it adjust Idle by it self . It adjust by closing way or blocking the fuel to pass and go to the engine.then the engine dies .

Sounds like your timing belt is one tooth off on the cam, this I have seen before especially if it is a twin overhead cam. One tooth off will make it idle really low when stopping at the light especially if the engine is warm.

this is your problem:

Here are the most common causes of surges, stalls at stops, low erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue 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

replace the engine coolant temperature sensor...top left side of engine...look for GRY/RED and LT GRN/RED wires
rate me fixya!
thanks
