this is just a thought, since i had a similar problem with mine a while back.

The fuel pump has a wire that is connected with the oil pump switch, if theres an oil pressure problem, it will kill the fuel pump so thus shutting off the motor. Well, what was wrong with mine was not actually a oil pressure problem, but one the the wires had warn through and was touching the exhaust and when the exhaust got hot, it killed the fuel pump since it made it think there was an oil pressure problem. Just an idea.

If you check what 83Coupe says and that doesnt fix it, check the ground to the pump. You may have to drop the gas tank.
