sorry I don't knwot he codes off hand but you definitely need to identify them and fix them before moving forward, be sure to ppull and clean al your electrical connectors as corrosion can be an issue, that being said sounds like the car dies after warming up, I have found a few causes fro this, the first is the CHTS (Cylinder Head Temp Switch) it's located on the bose of the drivers side engine head behind the timing cover, it can be done without pull the plate but is a huge PITA, the other problems all involve part failures with heat, fuel pump, coil, and ignitor are a few
