When i start the car up and let it heat up, it cuts off. Someone told me ignition module or crankshaft position sensor, but i'm not to sure what it could be. It starts up fine, but cuts off when its hot?????

before replacing the ignition control module i would rather you check and replace the cheaper parts. first off you should check the resistance of the spark plug wires. they should be 7000 ohms of resistance per foot. move the wire when doing this. check when wires are cold and again when hot and vehicle stalls. do this as fast as you can.

what did you find? what are the condition of the spark plugs.
