I find the same occurs on my FineOffset HP1000 clone - it happens to the device receiver.
My (unproven) theory is that the signals from the external and internal sensors which come every 16 seconds drift with respect with each other until they end up being transmitted at exactly the same time and the receiver can not discriminate them. After half a day or so the situation recovers and is fine for a month or more.
