Car will run for a few miles then either dies suddenly or won't start back up after turning it off. No spark until everything cools off for awhile. Then it fires right up.
Since the car was dying and starting at the same intervals, I figured it was heat related. And since there was no fire when it would die, I figured it was either the ecu or something in the distributor. I went with the cheapest of the two and changed the whole distributor seeing as how the distributor life was 150,000 miles anyway. Not sure exactly what it was that was getting hot and shutting down, but it fixed my problem.
