2002 CHEVROLET SUBURBAN 1500 Engine Problems

WHETHER IT'S IDLING OR DRIVING SHUTS OFF I REPLACED THE FUEL PUMP AND THE WIRING HARNESSES THAT COME WITH THE FUEL PUMP AND STILL NO AVAIL IT'S CAUSED A LOT OF TIME OFF OF WORK AND A LOT OF HEADACHE I WORK FOR A REPUTABLE DEALERSHIP I WORKED ON VEHICLES FOR OVER 40 YEARS

ON TWO SEPARATE OCCASIONS, MY FAMILY AND I WERE COMING HOME FROM TWO DIFFERENT TRIPS. THE FIRST TRIP WAS TO NEW ORLEANS FROM SOUTH TEXAS. ON OUR WAY HOME, WHILE DRIVING ON THE EXPRESSWAY, OUR SUBURBAN SUDDENLY TURNED OFF. WE WERE DRIVING ABOUT 70 MPH. THE DRIVER IMMEDIATELY PUT THE VEHICLE IN NEUTRAL AND STARTED THE VEHICLE AGAIN. IT TURNED ON. WE PULLED OVER TO A RESTING AREA AND OPENED THE HOOD, BUT WE WERE UNABLE TO DETERMINE WHAT CAUSED THE MALFUNCTION. IT HAPPENED ONCE MORE WHEN WE GOT HOME. THIS TRIP WAS DURING THE WEEK OF JULY 20TH, 2015. THIS PAST WEEKEND (MARCH 12-14, 2016), WE DROVE UP TO SAN ANTONIO FROM SOUTH TEXAS. WHILE WE WERE IN SAN ANTONIO ON THE EXPRESSWAY, THE VEHICLE TURNED OFF AGAIN. AGAIN, THE DRIVER PUT THE VEHICLE IN NEUTRAL AND TURNED ON THE VEHICLE AGAIN. WE WERE ABLE TO SAFELY PULL OVER...

TRAVELING ON HWY 35 IN DALLAS TEXAS AND MESSAGE APPEARED ON INSTRUMENT CLUSTER "REDUCED POWER MODE". VEHICLE SPEED DROPPED TO 20 MPH (POSTED SPEED WAS 70 MPH). HAD TO HAVE VEHICLE TOWED TO DEALERSHIP AND A FIX HAS NOT BEEN DETERMINED. THE DEALER SO FAR HAS CHARGED ME $900 AND IT DID NOT FIX IT.THIS SAME PROBLEMS BEEN POSTED ON GM FORUMS, GM TRUCK FORUMS WITH THESE SAME RESULTS. THERE ARE HUNDREDS OR MAYBE THOUSANDS OF COMPLAINTS FOR THIS ISSUE. IT IS VERY UNSAFE. *TR

WHILE DRIVING ON THE HIGHWAY, THE ENGINE JUST DIED. IT DOES IT ON EXTREMELY HOT DAYS AND AFTER DRIVING FOR LONG PERIODS OF TIME. THERE ARE NO WARNINGS FOR THE ENGINE CUTTING OFF AND IT IS AN EXTREME SAFETY HAZARD WHEN IT SUDDENLY LOSES POWER. IT LOOKS LIKE THIS SHOULD BE A SAFETY RECALL ISSUE AS IT IS A COMMON OCCURRENCE ON THIS VEHICLE. *TR
