Presently parked, temp 85 degrees with some wind. Fridge temp is 47 degrees running on 120v.
To me that is not an acceptable number.
Agreed. Something is wrong. The blue light should not be going off. Sounds like you are losing 12 volt to the fridge as the control is run by 12 volt regardless of what power source you have it on. Check the connections in the outside vent area if you can see them.
