Won't stay running while driving
I have a 2003 Rendezvous and when it starts it runs for a short time and then shuts off. Had a locksmith make a new key and program it to the car. Car ran for about an hour and then the same problem all over again. It will start right back up and run for 10-15 minutes and then shut off again. If I wiggle the key in the ignition it will continue to run for a short period again then will have to keep wiggling it. Put it on a computer and can't determine problem. Car has approximately 179k miles on it. Any recommendations ?
