Motor starts runs for awhile then dies - 1994 Ford Ranger Supercab

check your AC compressor

sounds like it could be a coil issue after its been sitting for awhile it starts again correct? when its running the coil will warm up and if there is a small crack in it anywhere it will seperate and loose its contact therefore interupting the spark for the engine and it will die. or it could be a bad fuel pump or even cheeper yet check the fuel filter.

I had a similar problem. Nissan sr18di engine. car would run fine and randomly engine would cut off and only start after 20 minutes. Changed distributer
fine since

Sounds like a fuel problem. The electronics shutting down are the result of the dying power. Start by changing the fuel filter. If that doesn't work; I'd look into the fuel pump.

Replace crank sensor

Try removing the idle speed motor on side of throttle body, and spray it clean, as well as the port it came out of, with throttle body spray cleaner. Don't pull and extend shaft of idle motor, just leave it in position it's in, and make sure you don't lose small "O" ring on idle motor. Re-install and try it. If it cures it for a while, then starts to do it again, replace the idle speed motor.

next time it dies check for spark, they have bad contorl modules, when they get hot they die,i would start there,also when you replaced the fuel pump did you replace the wire harness plug to pump? the was another problem was the connector melting and looses contact, hope this helps.

have your catalitic converter checked

The ck engine light should not be ignored, what sensor was shown to be bad ? Have it scanned again and replace the sensor that is bad if it still runs rough you might want to consider a tune up. Plugs, wires, fuel and air filter's and clean the throttle body with some gumout. It could also be the IAC motor Idle Air Control. Good Luck

Quite a few things can cause a car to die after idling for awhile, but if you have verified that the fuel pressure is actually dropping when the motor dies, the likely culprits are:
1) Electric fuel pump in the gas tank is bad
2) The fuel pressure regulator (on the throttle body) is bad
3) An electrical problem in the power to the fuel pump (like a bad fuel pump relay or lose ground wire to the relay's circuit)
