Lots of thoughts... Which ones do you want?
Might be completely normal, might not - you haven't given enough details one way or the other. All I can conclude is the transmission is probably shifting in and out of overdrive, most likely. Might be engine management, gear/drive ratio, load, terrain, altitude, or maybe, nothing at all.

What engine, trans, tire size, gear ratio?
Any history on the trans?
Any recent changes, like larger tires or trans work?
Rain storm, pressure wash, flood, fire, pestilence?

Most likely the Transmission Range Sensor (TRS) is failing. It's located on the driver's side of the trans. It is the only part that has a wiring harness attached.

Yes, it often gets worse as it gets hotter.
I once was trying to catch a TRS doing this. I had a vehicle that occasionally would act up. I drove it 500 miles one day trying to make it do this. I finally gave up. It happened as I was turning into the parking lot.
