I would look at the TPS, this seems to be the symptoms of one going bad. My dads Ram displayed the same symptoms, replace the TPS and ran much better, no jerking on the highway

IAC no not that
The IAC is for idle control now you’re TPS possible but I don’t think so at high speeds.
One possibility is the ECM I think that’s the name your computer when my ECM was going bad that was one thing I was getting stuttering at high speeds. I was also getting bucking, hard starts just a strange running engine.
Not sure how you test the ECM?
I would also suggest the O2s
