Empty Top End

I have a 97 2wd PS that is totally stock. It has 150k miles, mostly pulling a trailer with no mods at all. It still has stock exhuast, torque converter, etc... I pull a 7000# toy hauler now. hills i used to pull at 55mph in 3rd gear 2500 rpms i am now only able to struggle up at 45. It seems like i am empty in the top end recently, turbo doesnt wind up as much and the gas mileage has gotten a little bit worse. Lite without the trailer even struggles to get after it some times. This change has occurred over the past 12 months or so. It also seems to shift a little abnormally but that might a different issue. i checked the tranny fluid and looks a little overfilled from the last service. I changed the usual air and fuel filters with no luck. Any ideas on what i could check next. I had read previous that the cat or muff can clog over time. Is this a possibility? I also hear the torque convertors are prone to fail on these trucks, does it sound like symptoms of TC failure?

i suppose the cat could be clogged. if you have one anyway.

also, pull the intake off and check the turbo for shaft play and oil leaks. turbo may be done for?
