Obviously there are many threads on this topic, this one seemed like the most similar to my issue so here goes-

I'll get the Harry Potter bolt and/or Check Engine light and go into limp mode on my '07, but ONLY when off roading? At first it seemed like it was only in 4Low, but last time out it came on even in 4H and once in 2H.

I just have to shut off the motor and start right back up and I'm good to go until it happens again anytime between 2 and 20 minutes. Once I get back on the Highway the lights go away and it drives fine.

I pulled codes and it lit up: P0344, P0340, P0652, P1628, P2127

Any guesses from interweb land?
