2001 Gmc Yukon Denali About 8 Mos You Make Sharp Turn Ex U Turn Truck

I have a 2001 Yukon Denali and for about 8 mos or so, if you make a sharp turn, ex. U-turn, the truck sounds like its going to cut off and a few times it has, I have asked many mechanics and no one is sure. I have been told possibly the alternator, maybe a knock-off switch, the throttle is dirty, none of those have been the issue, it's still doing it. Can anyone help with this or heard of anything like this? Any information will be greatly appreciated, thanks in advance.
