This could be caused by a defective or glazed power steering belt and or belt tensioner, that is causing the belt to skip. This is actually pretty common.

I was think of perhaps a bad sensor in the AWD system. This would send a bad/incorrect signal to the control system.

Mine did the same thing and it ended up bieng a bad gear in the center differential. Had to have it replaced. Spendy, but fixed the problem.
