AM2302 - DHT22 temperature and humidity sensor stops working

Has anyone else had a temperature & humidity sensor model AM2302 - DHT22 stop reporting until it is unplugged and plugged in again, but all other sensors on the board still work fine? Any tips appreciated? It will work fine for 3 hours or so and then quit. I tried changing the time from 1 minute to 5 minutes for taking readings. I tried a second sensor. Thank you.
