My 1995 mustang 5.0 bucks and stalls. evap problem?

As when an ignition module cuts off, then after cooling off, works again.
As when a faulty alarm relay cuts the engine out intermittently.
Many new parts in there now, is the distributor pickup coil new too?
Many more parts can be replaced at random without diagnosing. To save time and energy, diagnose. When it is having a tantrum it is time to check, motor needs fuel, spark, and compression to run and by what is happening, one needs to find which is absent, which keeps the motor from running.
Does it have spark, injector signal? A 12V led test light or a noid light is used to detect the quick electric signal.
My opinion is it's electric issue, ignition component failing (pickup coil, control module), alarm, and/or possibly the ignition switch.

fuel filter? bad ground on the coil?

the iac sensor is along the side of throttle body , did you give the throttle plate area a good cleaning out this is where the air path is for the IAC sensor , a lot of idle problems have been fixed with a can of throttle body cleaner and few good squirts of the stuff down the hole

Very late but for anyone else with this problem. I used to have this occur when I drove around for a bit. I'd drive and after 5-20 mins the car would just stall on me. It wouldn't start immediately and sometimes just waiting an hour or 2 and trying again made it start and drivable for a few minutes again. The problem was the ignition coil. I spent over $1400 changing parts to find out it was an $18 fix and took 10 mins to swap out. If the rpms do jump around a lot then yes the stator would be the problem. If it just stalls even while driving, it's the ignition coil. If neither, test the voltage regulator. Hope this help. Happy driving!!

Start with checking all your fuses, after that it could be a lot of different things. Good luck...

1996 EXPLORER This TSB article is being republished in its entirety to include the 1995 4.6L Thunderbird/Cougar. ISSUE: After a 1-4 hour engine soak time, long crank times and/or long crank to start followed by a stall may occur on some vehicles. No further stalling or rough idle will occur after the engine is running. The long crank and/or stall may be due to the Idle Air Control (IAC) Valve sticking.
ACTION: Replace the IAC Valve with a revised IAC Valve if no Diagnostic Trouble Codes (DTCs) are present. Refer to the following Service Procedure for details.
SERVICE PROCEDURE

1. Perform normal diagnostics and correct any DTCs as required by referring to the appropriate year Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual.
2. If no codes are present, replace the IAC Valve by referring to the appropriate model/year Service Manual, Section 03-14. Refer to the following Idle Air Control Valve Application Chart for proper IAC usage.

The power supplied to the fuel pump, ignition coil, fuel injectors and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD):
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump,ignition coil, injectors and those parts of the power module.  This causes the engine to shut down.

Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.  Hope this helps, and did you try to retrieve any DTC codes?? Be glad to help friend.

My 1988 GMC jimmy with V-8 and automatic transmission w/ over drive would buck and **** at low speeds. The problem was identified by a FixYa guy as a transmission problem and suggested I try adding a Lucas product transmission additive at about $4. I did that and I am amazed that the old truck runs smooth, even idles better and does not stall when I go to reverse.

I think that the problem comes from the alternator.
