Power loss experienced climbing Colorado Pass pulling 6,000lb. 5th wheel with a 2002 CTD Auto. Usually pulls pass at 50-55 mph, but twice now the engine just losses power and won't go over about 1600rpm or 35-40 mph. No white smoke noticed and fuel filter just changed along with air filter and oil. Pulls a 3,000 lb. boat without trailer over pass just fine. Could it be lift pump or injector pump or ? Still under warranty, but want to get any TDR knowledge before dealer starts looking at it.
