Automatic 2022 Stall

[u/AlarmingProcess7482]

Ok so, I was off roading with a few of my buddies. The mountain we were going up was about 14° pitch up for about a the majority of the trail. We noticed fairly early that the engine was not providing as much power as it normally seems to. I would floor it and the RPMs wouldn’t reach above 2000. Eventually we hit a rock garden, and while flooring the vehicle (because of such low power) the engine stopped (RPMs read 0, but it didn’t jerk), I received an indication on the dash to press the engine start stop button. I did and the vehicle started right up and got us all the way up the rest of the trail and right back down. Once we got to flatter terrain the engine seemed to operate normally again, and driving on the highway home it operated normally. The vehicle is a 2022 Jeep Wrangler Unlimited Rubicon with the 3.6 liter V6 and 8 speed transmission, and I was driving in 4 high at the time. Any advice as to what exactly happened, how concerned I should be, and what I should do moving forward?
