power loss

power loss
I was towing my jeep this weekend and my truck acted up 2 or 3 times. I would lose power and have to come to a stop. I had my pocket scanner with me. It showed p0300, p0131, and p0151. I believe it also backfired once. I've also had issues with it idling only when in drive/reverse but not in n/p. Not sure if this is related. Thanks for help in advance.

We had a GMC that came in few months ago.. it was a firefighting rig that ran the nastiest fuel those guys could find. it misfired, ran horrible, pretty much what your describing. i got misfire codes and that was it. i tried plugs and wires and the back cylinders were super fowled. ended up being a fuel pressure regulator that fixed the problem, they tend to be a common failure on these trucks.
