It dies like someone turns key off, this is leading to spark. Somehow, your losing spark for long enough to kill the engine. If it was fuel related, it would stumble a bit, then die. Let me pull up some schematics, and I will get back to you. When you checked for spark, how are you checking? These cars have distributor issues. And its intermittent. Usually once it gets hot.
