Starts then dies after it gets hot.

Just a wild guess, but many years ago some Ford vehicles would conk out and then restart later after they cooled down. (Spark quit.) It turned out to be the ignition module mounted on the inner fender well. It was such a common problem, I remember seeing replacement modules on the rack at Kmart as if it was a part that was expected to fail often like an air cleaner. They were a silver ribbed metal unit about 4"x6" and 2" thick with a wire harness or two that plugged in. I would throw snow on mine to get home! Hope this helps.

Yes sane thing happened to my 94 and it was the ignition module justlike Hornet said also.
