2000 suburban stalls when driving @ 35-70 mph usually when making a slight turn (like getting off on an exit ramp). Typically, a key down and key back up will work to get it runing fine again. The probelm may not havppen for a few months and then it will occur out of the blue. I don't get a service engine soon or anything. No engine codes are set. The vehicle has 200+ miles on it and in general hs been reliable.
