I have a 2001 Galant. After a normal start up the car just shuts off. If I wait about five minutes or so it will start up and run fine. The check engine light comes on for awhile then shuts off. The only thing I have found in common is that it happens when I park with the front of the car at a slight downward angle. I thought it was the oil sensor cutting off the fuel because I was a bit low on oil but I add oil and it is still happening. Other than that I see nothing wrong. Any suggustions would be greatful!
