I've seen something similar. Clean and lube the tracks and rollers. If that doesn't do it, it's probably a wear or internal lubrication issue.

Thanks creek side. It wasn't the door as I could open and close it easily with one hand with no binding. I took down the motor unit and brought it inside to my work bench, tore it apart screw by screw and connector by connector, and gave it a good cleaning. Put it back together and hooked everything up - works perfectly now! I think it must have been oxidation on some of the internal connectors, or it could just be that taking everything down loosened up something that may have been binding a little on the screw drive. Now I'll just have to wait to see how it works in the summer...
