I would definitely consider this a fuel problem, either water in the fuel, or dirty filters.??A dirty?cannister filter can restrict total fuel flow in a way that limits engine power, and this would be most obvious while climbing a hill.? Change both filters and consider cleaning the fuel tank suction strainer.
A remote possibility is a clogged vent line on the fuel tank.? Driving the car up the same hill with tank cap removed would be a good test for that.

Wonder if this is more likely to be engine or tranny? I'm still too new to the klatta klub to know if a diesel can act this way. As for the tranny: Recently, I checked the fluid and found it barely on the stick. Due to how difficult it is to get a reading on the stick, and thinking its being probably a quart and a half low would allow me to gingerly drive it to the store, I tried to climb our steep but short hill leading out of our home. I felt significant loss of power in a sort of on-and-off fashion. Cringing, I surmised this to be tranny slipping. I shifted to neutral and coasted back down the hill into my garage. So, can low tranny fluid cause this sort of "slipping"? By the way, the tranny leaks at a fairly significant pace - hence its low-ness.
