SOLVED!
After replacing the Thermofuse, eyebrow board, main board and electrode/ignitor, the problem still wasn't fixed.

Mine measured 44.6 consistently but given there's really not much left to try to replace I went ahead and replaced the entire valve assembly, inclusive of a new valve solenoid. Good news, problem solved, fridge stays on all night and I can now move on with my life with a functioning fridge. And now I have a box full of replacement parts I can use in the event the fridge starts acting up.
Hope this helps someone who has this problem with one of these DMR702 "Renaissance" gems in their rig.
