When you stop and put gas in the tank, it takes several tries to start the car! You have to Rev the engine really high to keep it going, by revving the engine while other foot on the brake so you can put the car in Neutral or drive so that it will stay running! Usually takes about 3 trys and then it starts! And it only does it when fueling, you can take the gas top off any other time and put it back on and that doesn't affect starting the car.
