I had a very annoying problem on an old F-150 truck of mine. I am a pretty good old school mechanic and went through the long trail of diagnosing. Most people fighting an intermittent problem, choose to "Shotgun repair" all the suspected components at once and never pin-point the culprit. They just fixed it with one of the many parts changed. I decided mine wasn't going to win and I would find the exact problem and add it to my book of wisdom. To save you from all the steps I took, I'll get right to the culpprit. It was as simple as the Distributor Pigtail plug that connects to the Ignition harness Plug. A slight bit of corrosion was present inside the plug. When the plug got hot(because it was sitting on the intake manifold) it would expand just enough to make the connection weak enough to kill the engine. Let it cool and it would start right up. I cleaned the plug and hit it with a product called Corrosion -X "which I swear by" and five years have gone by without ever happening again. .
Good luck.
