I am having the same problem. I also have a 2001. Although mine will do it on flat terrain to. I thought it was bad fuel and have changed filters, but it keeps doing it. I also replaced the two rubber fuel hoses that attach to the fuel filter assembly. That didn't fix it either. I drove it yesterday while it was doing it and checked the codes and there were 2: P0093 & P1345. I am stumped. I wish some one could figure this out. The truck has 120000 miles , but it had the motor replaced at 75,000 and it was sort of doing the same thing before they had to replace the motor. Now the warranty is out of date and I don't want to buy a motor.
