Had the same issue on my old K3. It crapped out on me during Field Day a few years ago, and we finished the outing on 10W CW. Found that the rig had the original tinned pins, and Elecraft support sent me the gold pins gratis, and once changed out, the issue never came back.

Could this also be a hot pin problem that is starving the PA for power? The pins on the PA were changed to gold on earlier K3 sets. A contest would sure stress the pins if they had some resistance. Dave K1WHS
