Electronic Problem with Ecostar VSP Pump

Pump will sometimes cut out out suction error. When I discover it the bowl is full. When I restart the unit "most" of the time it will go through a normal 15 second prime and then go into normal operation. However on occasion it will continue on prime mode for 15 minutes and cut out on prime fault. During this time the bowl is full and normal water is being returned to the pool.
I tried resetting the power hoping to reboot the computer. This corrects the problem for a few cycles but it will then again fail with no lack of water on the suction side of the pump. Is there a way to correct this or is it a sensor issue and if so can the sensor be replaced?
