If the dealer is just going to throw parts at it (which is the only way if the problem doesn't happen when he's looking), try the ASD relay. This is just a guess, but that suplies power to the fuel pump and the computer. The ignition just triggers it. If the relay 'sticks', that can cause your symptom.
