2006 Saturn vue only runs when u start it with the remote start. When u use the key it runs for a few seconds than shuts off.

Well that seems like it has to be something bad in the ignition lock cylinder. You're able to start the car by turning the key all the way to Start, but when the key returns to the ON position (normal position when driving), the engine stops like the key is in the OFF position. At least it works with the remote start for you until you can replace the ignition lock cylinder
