My 2012 Cherokee's engine won't shut off!!! Help

Okay, really weird but my engine won't shut off. I'm on a road trip and when I got to my destination it wouldn't shut off! There is nothing in the manual for it but tried the remote start, button even the key itself. Even disconnected the battery without avail. It ran for about an hour more and then randomly turned off after I got in and the key buttons got pushed in my pocket. I was out in the middle of nowhere so didn't push the issue. Today didn't have trouble starting it but again, it won't shut off. The company party line is to take it to a dealer but I have another day of driving before I get back home. I was hoping some jeep experts could help. Thank you in advance!

Dont know why it did it, and am guessing it is a Grand Cherokee, not a Cherokee?
Either way, to shut it off in the future if needed, There are various relays you can pull.
Fuel pump, injectors, ignition, etc.
Have a look under the hood in the fuse and relay box, and look at the relays so you know which ones to pull.

Not really.
I have had more vehicles run with a battery disconnected, than not.

I believe it's because of the Jeep's alternator. Once on and engine running, the alternator is the primary device that supplies electrical power to the Jeep; the battery in turn, is now the secondary source of electricity.
