I live in AB Canada and it was about 10 below zero Celcius today. I put the unit in AWD because it was really icy and was driving around town shopping for about an hour. Suddenly, all the dash warning lights went on and the unit lost all engine power. I shut it off and restarted it and the engine light stayed on. I just had the oil changed but checked the oil and it was good. Both the oil pressure and temp gauges were at normal, and the engine regained power so I drove home. When I got to the house I shut the unit off and then restarted it, and the engine light did not stay on this time....any ideas as to what the problem may have been?? Oops - it's a 2004 GMC Envoy - 6 cyl.
