I, too, have seen this spurious KAT500 retune problem. I'm running a similar setup: K3->KPA500->LP-100A->KAT500->coax->balun->ladder line->hf doublet
I'lll be happily working 75M and all of a sudden the KAT500 starts re-tuning, and with the LP-100 alarm going off and the relays chattering in the KAT500, it sounds a bit like all hell breaking loose. I reverted the KAT500 to firmware version 1.32 and the problem *seems* to happen less often... That could be my imagination, though. Also I think that this has happened in MANUAL mode, as well as automatic. Perhaps it would be useful to have an option to only re-tune during the first few seconds of transmit?
