This car will start and run just fine for about 10 minutes and then it just shuts off. You can wait about 15 minutes and it will start again and 10 minutes later it shuts off again. It just will not stay running. I have replaced the fuel pump, strainer, and wires in the tank. I have also replaced the ignition coil module under the coil packs. None of this has solved the problem. Also the only code the computer shows is 12, which is system normal. Would you have any idea what this could be. I just don't want to spend a fortune replacing things one at a time. Thank you.

I keep suggesting this for stalling, and I know it can't always be the answer, but I've had two cars now, including this one, in which replacing the crankshaft sensor cured stalling when hot. Unfortunately, this car is a bit tricky, with the sensor behind the crankshaft pulley and must be aligned with the reluctor vanes on the back of the pulley.
