my mom's 2019 suburban premier 6.2 was on a roadtrip, and on the way back, decided to start pulling power over about 2500rpms, but there is no check engine light. the truck has about 169,000 miles

So what did you check? Did you put a scan tool on it and check the usuals?

the question is what might be the issue

Reach into the glovebox and pull the OBDII adapter out and plug it into the port, fire up your Torque Pro app on your phone and have a look around...

Fuel Pressure, LTFTs...

could be many things maf, transmission, fuel injection, sensor, really hard to say until you get a code
check for a history code if the check engine light came on and went out you might have missed it but it should be stored.

Back in 2018 my son's 2011 scion did the same thing, no codes and the car would not go past 2k rpms. I changed out the coils and that fixed the issue. I don't think a 2019 vehicle would do that with out throwing a code.
