The fact that the problem clears on stop/restart makes it seem more like a limp mode problem then a mechanical issue with brakes. I can't make a case that stop/restart would somehow relieve trapped brake hyd pressure. Are there any other codes?
My '08 3.0si would go into limp mode displaying 4x4, DSC, and other messages, engine revs would jump as trans downshifted. Stop-restart would make everything normal until the next event. My problem was an intermittent crank PS. I found the code w/ISTA. There are many possible causes for intermittent, near complete power loss.
