If it is stopping on the way up you need to check your door springs and also the drive gear. The drive gear is white nylon and is just in front of the motor. It may be stripped.
If it is doing this on the way down your door sensor may need to be aligned. Make sure they are pointed at one another and that the small light on each one is lit and not flickering.
