As Ozy said low fuel will definitely shut it down and as he also said many other inputs for it as well such as door ajar not sure it will even start at all with that seems to me I ran into that one time. Was loading the truck with it off then left the door open well not latched and tried to rs it. Brake pedal depressed is another one iirc, just pulled up the manual for my 2017 below is a list of items from the manual
How To Use Remote Start All of the following conditions must be met before the engine will remote start:
