Some things to check:

Timing (too much advance) Fuel system--too lean. Check pressure and injectors Carbon build up can increase compression--try a gas additive designed to burn carbon deposits, and you can switch to a higher grade of gas. Cooling system problems can cause engine to run hotter than normal and knock.

Also, don't lug the engine, downshift your A/T manually into a lower gear when climbing hills. Probably the lowest gear if you are only doing 15 mph.

Unfortunately, it sounds to me that this engine needs a rebuild, it should be able to pull faster than 15 mph on a grade when in the right gear.
