I was leaving a restaurant and as I was crossing the intersection my car shut off ,I got it started and as I got to the red light it shut off again so had to keep my foot on the brake and gas at the same time. Once I got back on the interstate I had no more problems. About 6 months later I was at mcdonalds drive-thru at 2am when my car shut off, I coasted into the closest parking space and my car locked up and I had no power at all and I was locked inside I manually unlocked my door got out of my car and I had to call aaa. My car would not crank when aaa man tried to jump under the hood, he had to take my backseat out to jump start it, he got it started and he told me he couldn't understand what happened. On another occasion my gas pedal sticks and I had to pull over and shut my car off and I waited about 5 minutes and started my car up and it was fine after that, and my car still shuts off most when I am idling or going slow thru town and my service stability warning steady runs, I turn the reset button and it comes back on , please help me fix these problems because I love my car.
