Any codes ?
Without any codes or more info... I'll throw out Engine Coolant Temp sensor...
If you have an OBD2 scanner that lets you look at data (I have an Autel.. like 80 bucks..or you can do a 13$ plug in Bluetooth and the Torque app or similar on your phone...) you can look at the ECT when you start it cold (should be the same temp as where it is parked) and see if the rise in temp it shows matches the real world engine temp. Warmed up...it should show around 180-190F(82C-88C)
It the sensor says the engine is "cold" when you know its really "warmed up" ... Bingo
I don't think you can not go by the dashboard temp gauge... to the best of my knowledge, they aren't the same... (Haven't had the truck long nuff, nor read deep enough into the FSM to know for sure if this is true or not...)
