After disabling auto shutoff as usual I noticed the engine shut off at my first stop. I pushed the button in a few times and it made no difference - the light stayed on but the truck shut off at every stop. I also noticed there were no lights indicating whether I was in 2 wheel drive or 4. I tried stopping, putting truck in park, shutting down and restarting to no avail.
Luckily disconnecting the negative terminal on the battery after I got home cured the problem.
