Good morning I am Reggie and will do my very best to help you. When this happens do any other lights come on other than stabilitrak? When you say lose power does it slow to a certain speed no matter your throttle response? I would describe it as like your gas cable come loose and it hung the throttle open barely above idle your speed would be 35mph or so and mashing the gas does nothing? Am I right?
If so tell me what you do to get the car going again, do you shut it off and restart fine?
Okay i believe i know where your problem may be, at the dealership are they saying they find no codes i dont understand how they could tell you there is no problem. If the light came one it would have set a code and left a recorded piece of data when the problem occured. What are they saying in regards ***** *****
On a vehicle like yours i see alot of throttle bodies or acclerator pedal problems, the electonic drive by wire system is composed of the throttle body, and your gas pedal, there are sensors in each that record position actually two sets of sensors that work opposing to each other if the computer sees a minor glitch in any of these sensors it goes into limp mode which you describe perfectly
Very well sir my opinion is that you have a problem in your electronic drive by wire system that is causing your vehicle to go into limp mode and that fact that you restart it with no problems goes to further strengthen this opinion. This opinion is based off comparisons to pattern failure records and your description of the problem
Thank you sir may i assist you any further
