I have the same problem with my 2010 Duramax, I turn off the traction control and it stops the porblem when it happens but, the stabiltrack light stays on. Trying to figure this one out myself.

Have the ABS module scanned for codes. The last reduced power, stabilitrak was a steering centering sensor. The sensor showed the Yukon was making a right hand turn while the truck was steering straight. Needless to say the module was trying to correct for the turn, but the driver wasn't turning.
