Most likely and cheap to change out and test run.

Any problems with acceleration?

Fuel filters are often first go to item for power loss issues.

11k on the filter's, yes they need changed......100% sure that is your problem based on your post. 11k on the filter's, how old/long since they have been changed?

I had a similar situation where the coach would buck going up the hills on the freeway. It was fine on the flats. I changed both filters when I got home and that solved the problem.

I too had problems with no power going up hill. Thought it was the filter too but turned out it was an electronic module to the filter. Took an hour to change at a cost of $100.
