Car runs, gets hot, then dies. Cant restart until cooler.

Pull the center coil wire out of the distributor cap and hold it near/up to a ground and see if it's sparking when you "loose spark"....

Then get an extra spark plug, disconnect any convenient spark plug wire, plug the wire into the spark plug and hold it to a ground and have someone crank it over, and look for spark. Be sure to hold the bottom electrode of the spark plug to a ground.
