IllustrationI WILL BE DRIVING DOWN THE ROAD BOTH HWY AND CITY. THE SUBURBAN WILL GO INTO REDUCED ENGIN AND LOSE ALL ITS POWER AND SPEED. I HAVE TO PULL OVER AND CUT THE CAR OFF AND RESTART IT AND IT'S FINE TO GO FOR MAYBE A MILE AND IT DOES IT AGAIN. THEY CAN NOT PIN POINT WHAT THE PROBLEM IS . IT'S VERY DANGEROUS.
