Throttle control valve

[Mojoarmy]

Brand new 3500 Larmie has been in the shop 3x for the throttle control valve. Dealership can't pinpoint what the problem is. Was asked if I was a 2 footed driver and no I'm not.... they tried to get the truck to fault but it wouldn't. Any ideas? Seems to happen at slow speeds... not more than 30mph.

What exactly is is doing? I am an all day two footed driver and I have had no issues with my 2019 3500....about 8,000 miles so far

Four times now while driving at slow speed... no more than 30mph in a parking lot or in town the throttle control light comes on along with the check engine light. The first time it did it the truck started to die but stayed running and then it was fine. The other 3 times it's felt like it shifts down into a lower gear and has tons of power and then goes away. The dealership said it's caused by using gas and break at the same time but they can't get it to do it. I'm not a 2 footed driver. They just rest and give it back to me. It's always done it driving slow and not using break. The check engine light turns off before I can get to the dealer where I bought it. It's just went over 2000 miles.
