I had this problem early on when the D300 & 70-200 first came out. It would happen quite often while I was shooting hockey and once in a while while shooting out side. I cleaned the contacts on the lens & body with Dexoit electrical cleaner. I can't believe it has not been mentioned here already. I have not had the problem since.
