When you're going up the hill your transmission should downshift. If it isn't, it's a shifting solenoid problem or a tcm problem. If it is downshifting and still bogging down, it's an engine performance problem

I had a similar issue, it went from occasional shuddering during slow acceloration (such as going up hill) to being more often occuring and eventually I was having a cylinder misfiring if I would try to accelotare hard through the "slipping/shuddering". It showed an error on my dash so I ended up taking my truck in and having all of my plugs pulled and replaced and a new coil pack and my truck has never run better.
Hope you can figure yours out!
