Don't know why turning it off would seem to clear the problem, but you have a hydraulic clutch. Pedal pushes a master cylinder piston which pushes fluid to the slave cylinder piston which moves the clutch plate. Pistons seals wear and the fluid seeps past the piston, having the same effect as releasing the clutch pedal. Or there might be a leak and there's air in the hydraulic system. Pumping the pedal temporarily "fixes" either. Sounds like that's the kind of problem you have vs trouble with the clutch disk, etc.
