The engine it's shutting off while driving, and after it gets cold it will restart, but after driving again another few miles it will shut off again. There are no lights on, so no mechanic to tell me what the problem is. I even called the dealer, and I was told that they can't diagnose the car because is no check engine light on. . I tried few different auto shops with no answer, so my car is parked in the driveway because I'm scared to drive it, I don't know how or when the engine will stop. . Another mechanic told me to drop the car to his shop but it make 2 weeks of work to find out the problem and I will have to pay for 2 weeks, and than to pay to fix it. It usually stops while in motion when close to the a traffic light, when I make a turn and always when I slow down.
