I have done both and still did not fix the issue. Shop had it several days last time and could not get it to reproduce. On the way home it did it...Shoot me!

I have a 2020 GMC Sierra 3500 Duramax with about 94k miles. I am having an issue that is intermittent. I took it to the shop and they could not reproduce it. The issue is it shudders/stutters RPMs from sitting at a stand still to accelerating on the roads to cruising down the road at highway speeds. The RPMs drop slightly and you can feel it in the engine like it was going to die but is oh so slight. Some days it is very noticeable, sometimes it is very often and sometimes rarely. No CEL's also. It died 1 time at a stop sign but immediately cranked back up. I am not sure what is going on, anybody run into this and found out what is causing it.
