2011 GL 350 loses power after driving 5-10 minutes
The vehicle has about 80k on it, and I just started experiencing the following:
The vehicle runs great for the first 5-10 minutes. After that, if I try accelerating, it shifts at pretty low RPMs (2k or less) even with it floored.
Shutting the vehicle off and turning it back on appears to "reset" something, where it then runs fine until it starts lagging again.
Does anyone have any clue what's going on here?

Had a SIMILAR, but not identical issue with my Sprinter, the Mass Airflow Meter was the cause of my issue. Keep us posted.

SOMETHING is putting it into "Limp mode".
EVERYOMNE will tell you what put their engine in limp mode, and it may or may not be what put yours there.
Seems the high hitters are (or seem to be):
The EGR system acting up
(and/or some sensor making the ECU "think" the EGR system is acting up)
The DPF filter (and/or the DPF filter pressure sensor)
People used to talk about burnt out intake manifold flap motors. (from dripping oil from eth turbo intake gasket)
Mine has done it is a few times. Each time is when it is cold and wet.
So far none of the time triggered a Check Engine Light, nor stored a code a regular OBD/CAN reader would show.
All times seemed random as to how long the engine had been running and always reset with a full shut-down and restart.
I am guessing the DPF pressure sensor since it is under the car exposed to the elements.
Since your sounds consistent, I would hope a GODD mechanic with a DAS system can figure out what is tripping it into limp mode.

From the write-ups I have read about people chasing these problems, even with a dealers help, it seems that man of these problems do not even store an error code.
What the F kind of control system software developer builds in safety routines and does not bother to capture the event causing entry into the routine?

One trying to hide emissions systems faults? Just a thought, I've seen similar on modern motorcycles many times in dyno testing/diagnosis/tuning. Heck I've got one mysterious one on my Jeep Liberty CRD right now, CEL on, FOUR different ODBII scanners show zero faults? It can be frustrating.
