Mine did the same thing. It began moving slower and slower. It is an easy test to check for a bad ground. Pull the switch pack out of the door, you do not need to remove the door panel, and run a ground lead to the black wire on the switch. With the key on, press the switch to make the window go up and down. If the window moves up and down quickly, than the ground is getting bad. you can use the same fix as I did.
