Default 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 belive it backfired once too. 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.

I checked pressure but I didn't check flow yet actually. I'm going to next day or so.

yeah either get or build a pressure gauge with a bypass, in my almost 20 years of diag experience ive fou8nd when you open the bypass if the engine rpm drops or hesitates or anything flow is low, regardless of any spec found.... The next thing i'd check after that is vacuum

Where do you find the spec for volume of flow? It filled a 17oz bottle in about 20 sec
