What do make to move? Atmega 644P malfunction? Noise?

I had something similar when some of the connectors oxidized. My DC motor spindle sometimes simply stopped or slowed down for a few seconds, without visible reason. Some grease for battery poles (an acid-free grease, get it from a dealer for car batteries) put into the connector pin holes is a great help in such cases. It spreads on it's self and the oxidization will slowly go away.
