2015 Suburban Sputtering

Hey everyone. My 2015 Suburban LTZ is sputtering like misfires when under light acceleration.....kind of a quick jerking as acceleration stalls. When you give it more acceleration it goes away. It isn't throwing any codes. I am running premium gas, so I'm not sure it is a fuel quality issue. I took it to my normal mechanic and he said "this is above our head, you may need to take it to the dealership...we can't figure it out. Fuel is only getting to half of your engine." While I don't mind taking it to the dealership, that is always my least favorite option. I was seeing if someone here has had this before and could give ideas, just so I am prepared for if the dealer starts trying to take me for a ride. I have about 93,000 miles on the vehicle. I tried to search the forum and saw some fuel pump ideas, but it was on older models.
