2003 CHEVROLET SUBURBAN Engine And Engine Cooling Problems

I HAVE 2003 SUBURBAN 1500, THAT KEEPS GETTING A ERROR MESSAGE "REDUCE ENGINE POWER". THE VEHICLE WILL ALL OF SUDDEN WHILE DRIVING, REDUCE SPEED AND I CAN'T ACCELERATE ABOVE 25-30MPH. I WILL HAVE TO PULL OVER AND TURN CAR OFF FOR 10-15 SECONDS BEFORE IT RESETS, HOWEVER IT WILL CONTINUE TO HAPPEN OVER AND OVER AGAIN! IT IS VERY SCARY AND DANGEROUS WHEN I HAVE MY KIDS OR MY WIFE DRIVE IT BECAUSE YOU NEVER KNOW WHEN THE CAR WILL HAVE THIS HAPPEN. STRANGELY, WHEN WE DRIVE ON THE HIGHWAY WE CAN USE THE "CRUISE CONTROL" FEATURE WHEN WE REACH 25MPH AND USE THE CRUISE CONTROL TO ACCELERATE THAT WAY WITH MINIMAL OCCURRENCES. I HAVE TAKEN THE CAR TO "2 CHEVY DEALERS AND 3 MECHANICS" NEITHER CAN TELL US WHAT'S WRONG! THIS IS FRUSTRATING BECAUSE WE ONLY HAVE ON CAR, AND WE KNOW THIS A "SAFETY HAZARD" AND EXTREMELY DANGEROUS...

MY SUBURBAN GOES TO REDUCED POWER UNEXPECTEDLY AND THE ENGINE WILL STALL CAUSING A LOSS OF POWER STEERING AND CONTROL OF THE VEHICLE. MY SUBURBAN HAS BEEN TAKEN IN TO THE DEALER I PURCHASED THE VEHICLE FROM ON FIVE OCCASIONS AND THE DEALER IS UNABLE TO FIX THE PROBLEM.. THE MOST RECENT TIME WAS 9/1/2011. IT WENT TO REDUCED POWER 10 MILES AFTER LEAVING DEALERSHIP AND STALLED AS I PULLED OUT INTO TRAFFIC FROM A RESTAURANT. A NUMBER OF CARS HAD TO BRAKE EXCESSIVELY AND SWERVE AROUND ME UNTIL I COULD ANGLE MY SUBURBAN OFF THE ROAD WITHOUT POWER STEERING. THE TRUCK WEIGHS 6700 LBS AND I NEEDED ALL MY STRENGTH TO TURN THE WHEEL ENOUGH TO GET OFF THE ROAD. I AM FEARFUL ABOUT DRIVING MY SUBURBAN AND THE HIGH PROBABILITY OF INJURY TO MYSELF OR OTHERS. *TR

TL*THE CONTACT OWNS A 2003 CHEVROLET SUBURBAN. THE CONTACT STATED THAT SHE STARTED THE VEHICLE SO THAT IT COULD WARM UP AND WITHIN A FEW MINUTES IT WAS ON FIRE. THE POLICE AND FIRE DEPARTMENT WERE CALLED AND A REPORT WAS FILED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHO ADVISED HER THAT THE FIRE STARTED IN THE LOWER RESISTOR CONNECTOR AND THE BLOWER MOTOR. THE VEHICLE WAS DEEMED AS DESTROYED. THE MANUFACTURER WAS CONTACTED AND AN INVESTIGATOR INSPECTED THE VEHICLE BUT DENIED HER CLAIM. THE FAILURE MILEAGE WAS APPROXIMATELY 132,000.

TL*THE CONTACT OWNS A 2003 CHEVROLET SUBURBAN. AFTER HAVING THE OIL CHANGED AT AN INDEPENDENT REPAIR SHOP, THE CONTACT BEGAN TO SMELL A BURNING OIL ODOR COMING FROM THE ENGINE. THE CONTACT BEGAN TO NOTICE THE VEHICLE WAS CONSUMING OIL EXCESSIVELY AND WOULD REPLACE THE OIL APPROXIMATELY TWO TO THREE TIMES A WEEK. APPROXIMATELY 1 YEAR LATER, UPON STARTING THE VEHICLE, THE CONTACT BEGAN TO HEAR A KNOCKING NOISE COMING FROM THE ENGINE BEFORE IT STALLED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT REPAIR SHOP WHERE THE MOTOR WAS BEING REPLACED. THE FAILURE MILEAGE WAS 140,000 AND THE CURRENT MILEAGE WAS 150,000.

ON THREE DIFFERENT OCCASIONS OUR 2003 CHEVY SURBURBAN HAS STOPPED IN THE MIDDLE OF TRAFFIC FOR NO APPARENT REASON. WE HAVE TAKEN IT TO THE CAR DEALERSHIP AND THEY HAVE CHARGED US TO PUT IT ON THE COMPUTER MACHINE AND CANNOT FIND ANYTHING WRONG WITH IT, WHICH LEADS ME TO BELIEVE THAT THERE IS SOME KIND OF DEFAULT WITH THE VEHICLE. THE LAST TIME WE WERE MAKING A 150 MILE TRIP FROM OUR HOME TO ANOTHER CITY, AND IT STOPPED 5 TIMES. WE WOULD HAVE TO PULL OFF THE HIGHWAY AND LET IT COME TO A COMPLETE STOP, AND THEN IT WOULD START BACK. NEEDLESS TO SAY I WAS VERY FRIGHTENED AND THIS IS REALLY DANGEROUS. I WOULD APPRECIATE YOU ALL INVESTIGATING THIS TO SEE IF THERE IS A PROBLEM WITH THE VEHICLE, SINCE NOTHING SHOWS UP WHEN THEY TEST IT. AT THE PRESENT TIME I REFUSE TO DRIVE OR...
