You need to use the Custom option from the Speed menu of the Motion Path behavior – and set keyframes for it.
Go to the frame(s) where you want the movement to pause and set a keyframe. Then go to the frame where you want it to start again and make another keyframe with the same value as the previous one.
Make sure the keyframe interpolation of the first keyframe is set to linear so there is no movement between the two keyframes. You will need to set this in the Keyframe editor – right click on the first keyframe and select Linear from the Interpolation options. You can always change the curve of the incoming and outgoing sections if you don’t want a sudden start/stop.
Note that you can’t use the Constant interpolation option for this as although you can get it to stop dead, when the animation resumes it will jump to where it would have been if there had been no stop.
Hope that makes sense.
