6.5L losing power

Greetings,
On a recent towing trip that involved lots of hills it seemed I was losing power.
Here is the details: 1994, manual trans, good boost, no smoke,no codes, 140k miles, recent air filter, recent fuel filter. Factory exhaust. Ceramic piston injection pump.
Runs like a top on the flats, no grunt on any hill with the trailer. This seemed to get progressively worse.I had to pull the hill in the trailer park in 1st gear.
If anyone can help I'd sure appreciate it :-)

@racer 55 6.5s don't have lift pumps. Truck was sold.
