You have to go through the same routine as we techs do to isolate the problem. Nothing can be diagnosed without actually confirming the symptom and problem. Your going to have to test the system WHILE IT IS DEAD for spark, injector pulse and fuel pressure. You are definately losing one or more of those things. Once you know what your losing, that will narrow down the possibilities and we may be able to help you more. You'll need a spark testor, a noid light for the injectors and a fuel pressure gauge ready to go when it decides to die.
