Yes, it seems that after a certain period of time, your gathering history is reset (this is what I call keeps track of what you can't gather from because you did it recently). I've never bothered to actually figure out, but it could be X number of hours after your last gather, or it could simply be a particular time of day each day for everyone (such as JP midnight).
Just cycling between 1 mining node and the 2 quarry nodes, or 2 mining nodes and 1 quarry node, will allow you to quarry constantly -- why are you not doing that?
