It doesn't stop running until the on/off button is pressed or until it runs out of fuel. I know because on a couple of occasions, I had my car valeted but took the key fob with me. The valet parked the car and shut it off, but he couldn't bring it back to me because he had no way to restart the engine without the fob. daa . . .
