Rubicon Loses Power in 4wd

So yesterday afternoon, I took my 2010 6-speed manual JK out for a spin on a rural road. There was a 1.5-2ft deep run off ditch along the road and I wanted to dunk my tires in it/ put some "character" on my Jeep.

Well, I put it in 4hi (was going around 15-20mph) and only had the right side get dirty. After a few seconds of driving in the ditch I said "ok that's enough, lets get out of this" so I gave it some gas, gently turned the wheel and all of a sudden, all of the power from the engine cut out! I saved the engine by reengaging the clutch, turned the wheels parallel to the ditch, and tried again with more speed. Didnt work because the engine lost virtually all its power.

I finally got out when I put more of my Jeep in the ditch and then gave it the most gas I could.

My question is: why did this happen? I thought my Rubi was invincible.

TL;DR Drives right side of Jeep in ditch, cant get out because engine loses power mid escape, dont know why.

Did you turn off your traction control?

That was one thing I didnt do. Would that have improved the situation regarding getting out of the ditch?

Not lifted, stock 32" tires, hasn't been regeared to my knowledge. What would be a benefit of getting it regeared?

Traction control did the same to me. When in 4 hi press and hold the TC button for about 5 secs until you hear a chime.

In reference to the regear...IMO a LOT of people add bigger tires and lift and feel their Jeep is still "allright" because of how it is on the pavement...off road is where your "gear shortage" really shows up.

I will now side with yes the TC should have been off.......

Did the clutch get wet? Did you engage the clutch while you were in the ditch?

Ah that is a valid point. I did engage the clutch when I shifted to 1st so maybe at some point it got wet.

it takes pretty deep water to get your clutch wet.

you were experiencing traction control, the only way to completely turn it off involves cutting wires. for instance, I could turn it off and do donuts in a wet field all day, but if I were buried in a mudhole and I mashed it to the floor, all 4 tires would NOT keep spinning faster and faster until I was bouncing off the rev limiter. mine is an auto, so things might be a little different, but I doubt it.

you were in 4 low right?

I was experiencing the same problem in this picture, only I killed the engine because I thought I hydrolocked.

this hole gets the award for being the most deceiving puddle in history, here is a sammie with a few inches of lift on 33's.
