so im lost on this one lol... went out did a little bit of very light 4x4ing some light mud mostly dirt roads with the explorer. started to head home and the truck just cuts out wont rev past 2k or over a 1/8 th of throttle and cuts out and wont rev. i check for codes and loose or broken stuff nothing seemed wrong or any codes.I pulled the neg and let it sit for 10 mins or so started up and ran great for about 15 mins and started doing same thing but has a code now but no light . Its throwing p1131 and p1151. IM gonna bring it to work in the am and put it on the modis and see what everything is doing kinda seems like a maf or some kind of metering problem .

i'm thinking MAF or related wiring...

Bank 2 sensor one is the sensor directly under the transmission, and the sensor throwing the codes

My bet is you snagged the wiring to it and broke wire, or, maybe even banged the sensor. It hangs down low-

Or it is also possible the wire is rubbing on the front drive shaft-I have seen this more than once.

ended up being the fuel line coming out of filter up to rail had collapsed internally and was limiting fuel psi to about 12 pounds and very low volume
