engine stall

[beez807]

I have a 351 m with msd coil and ignition. after driving it for a around 30 min it shuts off, i have moved the coil and igniton. i thought that it was the heat. also put on a new distrubutor. any other suggestions

When it stalls, get out and check for spark, if there is none at least you will have determined if it is a fuel problem or it is an ignition problem.

when it stalls touch the coil see if it is warm hot cold...coils can go bad and after a little while of driving they will heat up and quit working (had that problem many times) also check the "brain" module on your driverside inner wheel well...they also can go bad..try tapping on it lightly with a hammer or if you dont mind spending the money to see if it fixes it just replace it

Does it have a stock distributor? If so, that is a classic symptom of a bad pickup in the distributor. It acts as if someone reached over your sholder and thrned off the key and then when the engine cools down it starts right up.

Good luck,
