Transmission slipping?

I was offroad going up an small incline that was uneven. As I was going up I heard a quiet grinding type of noise and could feel it on the pedal, then it started to slip and i had no power until i put it into neutral and rolled back down. I was then able to move over and was able to make it up without any grinding noise or slipping where the ground wasn't uneven. I don't have any slipping on road even under hard acceleration. Could it be the transmission separating from the engine when the vehicle twists?

Only if all of the transmission to engine mounting bolts are very, very loose.

I dint notice it flashing. Doesnt look like it has moved, no leaks and full of fluid, and the temp was normal.

Rear Differential is my bet. Time to pull the plug out and have a look.

If it only occurred when you were hanging a back wheel from the uneven ground it may of been the limited slip differential slipping. If the clutch discs are wore it can act like an open diff and put all the power to one wheel. The power will go to the path of least resistance which is the tire with little to no traction causing the lack of propulsion at that point.
Pulling the plug will tell you little to nothing since they are fiber discs and non-magnetic. If you suspect clutches you need to at least pull the rear cover for a look.
But if you heard clunking and grinding I have seen clutch packs wore so bad that it allowed the spider gears to jump teeth on the side gears. If it did it enough you may them see metal on the plug due to damaged gears.
Either way you can buy a kit to rebuild it.

​​​​​​I don't think it's the differential because It still made that noise when I wasn't moving.

It has an open differential and I stopped and got out to see what the noise was because at first I thought it was the fan rubbing on something, so the noise was still there when I was in park.
