2006 MONACO RV MONARCH Engine Problems

I WAS DRIVING TO THE OREGON COAST IN THE MOTOR HOME WHEN I LOST POWER. J1850 NOT AVAILABLE APPEARED ON MY SPEEDOMETER AND I HAD NO PASSING GEAR. THIS COULD HAVE BEEN VERY DANGEROUS IF I WAS TRYING TO PASS ANOTHER VEHICLE.I CONTINUED DRIVING AND AFTER ABOUT 5 MILES EVERYTHING CORRECTED AND WAS BACK TO NORMAL.I HAVE TALKED TO A WORKHORSE WARRANTY SHOP,AND THEY SAID THIS WAS AN ENGINE COMPUTER PROBLEM.THE ONLY PERSON AUTHORIZED TO REPROGRAM THE COMPUTER WAS A WORKHORSE DISTRICT MANAGER,AND HE HAD BEEN MOVED TO THE EAST COAST.THIS IS A SERIOUS PROBLEM,AND WORKHORSE SHOULD BE HELD ACCOUNTABLE AND GET THIS PROBLEM FIXED WITHOUT DELAY. THANK YOU *TR
