Hi Mike, Did you check the powerpole connectors? On both sides: K3 and cable?
I experienced such power down when I changed my original 13.8V cord against a self made one, shorter and with higher cross-section to avoid the voltage loss in the cable. But the insulation was bigger than the powerpole inlet. As a consequence the contact did fit completely to the edge.
