From what I've seen thermocouples do fail but more often than not it is the wiring/connectors. Check the readings from any points you can between monitoring system and the actual thermocouple. Probably just a loose connector caused by constant vibrations.

Whatever it is you are going to need to go through troubleshooting to find it.
