2002 CHEVROLET SUBURBAN 2500 Engine And Engine Coolingenginegasoline Problems

I HAVE A 2002 CHEVROLET SUBURBAN 2500 4 WD WITH AN 8.1 LITER ENGINE WITH 67,000 MILES ON IT. IT HAS STALLED OUT 5 TIMES OVER THE LAST 6 MONTHS, NEARLY CAUSING A SERIOUS CRASH ON THE SECOND TO LAST ONE ON INTERSTATE ROUTE 80 OUTSIDE OF SPARTA, NEW JERSEY. THE ENGINE JUST STOPS AND I HAVE NO CONTROL OVER THE VEHICLE. I HAVE TAKEN IT TO TWO MECHANICS WHO HAVE NOT BEEN ABLE TO REPAIR IT. I AM AFRAID TO DRIVE THE VEHICLE. WHAT SHOULD I DO AND WHERE SHOULD I GO TO GET THIS FIXED. IT IS A LIFE SAFETY ISSUE NOT ONLY FOR ME, BUT MY FAMILY AND HORSES WHEN WE HAUL HORSES FOR OUR EQUESTRIAN ACTIVITIES. CAN YOU IMAGINE THE DISASTER THIS WOULD BE WITH PEOPLE AND HORSES ON THE HIGHWAY IF THE VEHICLE STOPS DEAD!!?? *TR
