Question YORK heat Pump

YORK heat pump installed in 1987. New Style board installed in 2002. Also, new discharge sensors installed in 2002. Now on new style board, it shows a 4 led flash code, pauses and then repeats. When power is removed from the board and re-applied, the system resets and begins operating correctly. This is temporary however. It may work correctly for 10 minutes or 10 days, accordingly. When it is operating right, everything is fine. The house becomes cool quickly. But, the fault may re-appear at any time. Any advice on how to solve this problem would be greatly appreciated. Thanks in advance.
