Yes silver,it happens at shutdown after my all day cooks and my hunch is the temp sensor. A friend at work had a similar situation only he had wild temp readouts ,he changed out his sensor and all was good after that until his control board took a dump. I have also noticed a strange whirring noise when the auger is activated to dump pellets, it almost resembles the sound of the igniter kicking on when the auger is told to send pellets to the burn pot. I'm kinda wondering if maybe i'm subject to the same fate my friend at work had with his pit boss?
