This morning, starting the CWT,  every few transmissions my amp was faulting with the indication of excessive driving power (~67 watts vs 33 watts normally).  Each time, it would fault once, then operate normally for a dozen or so transmissions before the next fault. Then, about 10 minutes into the hour, the faults stopped happening.  The K-3 showed 33 watts throughout

I checked the KPA-1500 log, and all it shows is the "power input" fault.  What could be causing this erroneous indication of excessive drive?  A sticky relay?
