I have had the issue while driving at 70 mph and car loses engine power as in total shut down, but still have all electrical functions. Almost got cleaned out by a semi trying to cross from the speed lane to the median 4 lanes over to the right, this has occured 3 times in the last 2000 miles, car will not fire for 5 minutes after stall, then as if nothing ever happened will turn
over as if nothing occured. dealership keeps telling me nothing wrong?
