I recently bought this truck. Is there a way to keep the truck running when I exit it with the key Fob. I do quotes all day and would prefer to keep it running. it shuts down automatically after a certain amount of time. 94 degrees here every day. want to keep it cool.

 

Probably not. My Traverse shuts down after 30 min. if gas pedal has not been pushed. It's how factory programs it, either to save fuel or prevent CO poisoning suicides.
Maybe the aftermarket has a reprogramming out there. Police and emergency vehicles probably don't have that feature.
