Power loss and high RPM

Anyone else have issue with truck losing power/throttle response during heavy acceleration?

I’ve been having this issue in my 2020 2.7 that doesn’t happen all the time, but seems to come in waves.

During heavy acceleration the rpm’s will jump up to 5-6k range, throttle response is reduced by at least 50%, and high rpm remains even after letting off the accelerator completely. There was one time the truck lost power completely with no throttle response at all, but kicked back in after about 10 seconds of letting off the accelerator.

Not sure if it’s a throttle body issue, or possibly transmission issue.
