If GPS signal is intermittently dropping off and coming back after some time, you could try increasing the Synchronization Holdoff Time (default is 30secs). The Synchronization Holdoff Time is the amount of time the AP will continue transmitting even if it has lost GPS signal. If the interruptions in the GPS signal the AP is seeing are short, increasing this timer will help to keep the links up. The AP must be tracking at least 4 satellites to maintain accurate synchronization.
You should also verify your APs are running the latest GPS chip firmware.
