Do this little test.
Shift into the big cog in the back. Then without pedaling, shift down to slacken the cable tension.
Pull the cable housing out of the frame stops and slide it back and forth. If it's gritty. It's causing you the problems.
You can do this to the piece of housing from the shifter to the frame (usually clean) and then the one around the seat clamp, and the last piece from the chainstay to the rear derailleur. The last one is usually where 90% of the problems occur. (most prone to dirt/water intrusion).
Spray some lube into the housing and slide it back and forth a bit. Wipe down with a clean cloth. Repeat until smooth. If it's too far gone, learn how to replace it, or take it to a shop.
