Your system may have check valves, which are intermittently stuck closed, creating a vacuum and not allowing the tanks to fill or empty. Any blockage to the outflow pathway (depending on how you set up your Fly High set up) will prevent normal filling or emptying.

Do the pumps simply not come on when they are not working, or do the pump motors make noise but no water is moving?
