Went for a little cruise today, after about 1/2 hour I was sitting idling and it quit, started right up again so I drove it home . It quit once more on the way but started right up again. I have been checking out the wiring because it seems to lose power to distributor ( my guess at this point) I will be checking out the complete ignition circuitry tomorrow. Is there any way it could be the module in the GM hei dist. I think usually when these crap out they go all at once. Any suggestions?
