Maybe the sensor right next to your thermostat has a loose connection or went bad. Never had this happen but that's what I'd check first.

Drive it hard, break it, and when you get to fix it you can trust it better.

If it slowly gains in temp, and then slowly moves back to cooler on a steady pace, it may be your thermostat.
