Chris, Have you confirmed that you have fire to the plugs even while it's dieing after it starts. Take one of the plugs wires off and have a friend confirm fire to them while it's dieing. It should still crank on 5 cyl. Have you taken the rpm relay out to see if the contacts need adjusting and cleaning. As a safety, the rpm relay senses the pulse coil out put in the distributor while it's turning and allows the relay to close which in turn turns on the fuel pump. DMCJoe or someone else may tell you how often the pulse coils goes out in the distributor, but mine went out last week. Symptoms were, it would run for a while and when the impulse coil wire heated up the car would die. Let it cool down and it would start up again and run just fine. After you have confirmed you have fire to the plugs, then Maby you should also direct wire the fuel pump by taking the white/purple out of the relay socket and clip jumping it to a known hot wire Normally brown. When you have cliped it to a hot wire you will hear the fuel pump running. Then try to start the car. Process of elimination.
