I've used my key fob to start the vehicle remotely a few times this past weekend and while loading the kids into the back, the Carnival would sometimes shut off as I walked from one side of the car to the other. I know there is a 10 minute timeout programmed into the start sequence, but I'm nowhere near that 10 minute mark when the car turns off. I haven't seen anything in the manual that explains this, so I'm going someone here may know why this happens or how to prevent it?
