HEI Keeps Dying - Help Please! - Third Generation F-Body Message Boards

Twice this summer while cruising my engine has died completely (with the tach going to a "zero" reading even b4 the engine stopped turning over). After replacing the distributor (GM HEI coil in cap) everything was fine for a couple months until it happened again today. I believe I'm burning out my module but I can't figure out what would cause it. I'm thinking:

1. Excessive engine compartment heat?
2. Excessive voltage to the distributor?

Thats all I've got. I'd love some feedback because the problem shows no symptoms, the car just DIES.

Thanks

The module needs the appropriate heat sink compount and also a good path to ground.

I had some bad grounding issues killing my 8-pin modules.

Does it restart after it dies, or do you have to replace the module to get it going?
Could be that you have a bad/corroded connection and each time you are working around the distributor, you are correcting the problem. Check wiring to distributor.
