I just picked up an 07 Tahoe, hopefully someone can help with this issue

... The remote start works fine throughout the day but when i go to start it first thing in the morning, it turns over and then shuts off, I've tried holding down the start button for a longer period of time and same thing. The truck starts up normally when i use the key after this happens. Once i start the truck with the key and turn it off, the auto start will start the vehicle.
