Sounds like maybe the fuel pump. Once it has time to cool it works again. Or a fuel filter

Sounds like a failing ignition control module (in the distributor). When it quits, check again for spark. If you have no spark that's my first suspect. HTH. -Jim

For years the problem your having sounds like a bad ignition switch ..


It was the Electronic Spark Control (ESC) up underneath the dash above glove box. Amazing! Never knew about that part and I've worked on a ton of GM's from the 80's. You can teach an old dog new tricks! Thanks everyone for your suggestions!
