Tried playing in some dirt today, and went to pull a 180 and when it started to turn, it had no power to the ground.

I know little about automatics, is this a torque converter issue?

nobody?

Any noises? Other symptoms? Does it just bog out?

Tires were spinning but u didn't notice so it felt
Like there was no power to the ground? You were low on fuel and all the went to one side of the tank so the pump sucked air?
You description is terriable so were all guessing tell we get more I comic what the jeep did...

The jeep stopped accelerating once I started to swing it around. I had maybe a 1/4 tank or so.

Something with the weight transfer, from centered to right, is causing this issue. Otherwise, it drives great.

Well try again with a full tank. Still got problems? The connector for the fuel pump (by the filter) gets dirty and corroded and causes random power loss.

1/4 hmm yea try again with more fuel, and could be when the weight transfers over the reared allows all the power to go to the tire with no weight on it???

no, this was like the car shut off.

so maybe an inferior designed fuel tank and pickup

When gas gets low in these things that tends to happen. Don't think there are baffles in the tank. That's probably your issue.
