While pulling a very steep mountain road, towing about 11000 lbs,in 4w low my engine temp went to about 220*. Shortly after hitting that temp my Edge juice shut/attitude turned off. Needless to say the sudden loss of power was not good. I did make it to the top of the mountain, very slowly. The next day the Juice fired up and has worked great. Is there a shutdown built in for over temp in the Juice?
