My 89 -5.0 shuts off after driving for 1 hour, it will crank but will not start, if I wait 30 minutes, it will start and run for another hour. Already replaced the module next to the distributor and didn't fix it. Any other ideas?

 

Here's an idea, post in the correct forum.

 

This forum is for the real 5.0 !!!

 

To answer your question, there is a module on the distributor( the one with the plug on it), that when it heat's up, it cut's out the spark. This is caused by heat build-up. Change out this module, and use the right heat grease when you install it.
