2003 Chevrolet Suburban 1500

DRIVING ON THE HIGHWAY AND I LOST ALL POWER. IT SAID (REDUCED ENGINE POWER) ON THE DASH. THIS HAS HAPPENED SEVERAL TIMES AND I HAVEN'T FOUND A MECHANIC WHO CAN FIX IT. I'VE LOOKED ALL OVER THE INTERNET AND THERE ARE MANY OTHER PEOPLE WITH THE SAME PROBLEM. THIS IS VERY DANGEROUS AND ALMOST CAUSED AN ACCIDENT. IT COMES OUT OF NOWHERE AND FOR THIS TO HAPPEN TO SOMEONE FOR THE FIRST TIME, IT'S GOING TO CAUSE SOME DEADLY CRASHES. *TR

JUST FINISHED DRIVING VEHICLE FOR 1 HOUR AT HIGHWAY SPEEDS WITHOUT INCIDENT. PARKED CAR FOR 5 MINUTES, UPON TRYING TO RESTART, THE CAR DISPLAYED "REDUCED ENGINE POWER" ON THE DRIVER INFORMATION CONSOLE. APPROXIMATELY 8 RESTARTS AND THE MESSAGE DID NOT DISPLAY. DROVE CAR 5 MINUTES AND PARKED IT FOR 1 HOUR, UPON RESTART DISPLAYED SAME MESSAGE, CAR WAS VIRTUALLY UNDRIVEABLE. 3 RESTARTS LATER MESSAGE NO LONGER DISPLAYED. THIS MESSAGE HAS NOW INTERMITTENTLY OCCURRED EVER SINCE SEEMINGLY WITHOUT ANY PATTERN. THE MESSAGE IS RELATED TO A FAILURE IN THE "DRIVE BY WIRE" SYSTEM THAT ALLOWS FOR THE ELIMINATION OF A PHYSICAL CABLE FROM THE GAS PEDAL. IT CAUSES THE CAR TO BE COMPLETELY UNDRIVEABLE UNTIL SEEMINGLY RANDOMLY FIXING ITSELF. *TR
