I had the EXACT same problem except mine was a bit worse... i would be riding down the road and the car would shut off..... I would be able to start the car by turning the key and holding it but when i let go of the key.. it would shut off.... it IS the ignition man.... TRUST ME!!!!!!!!!!!!!!!!!!! Go to your dealership and the part is like 30 bucks... you can do it yourself but i had them do it and they charged me 150 bucks.... it took like 10 minutes.... It jsut plugs in!!!! GOOD LUCK and keep us informed!!!
