Like mentioned before, the DB-37 cable is plugged into a module (not a bumper), the Analog board that attaches to the Analog module is called a bumper.
Also when you tested it in the morning, was there new code deployed, or was it "permanent" code with no new deploying?
Also, did you test different power wires/connectors from the Power Distribution Board to the DSC?

And finally recently our robot's wifi would decide to restart whenever I enabled the robot (happened to be for only 1 battery), but that battery's main terminal was loose which let the robot boot fine but when it came to draw power, it crumbled. So I would check any loose connections starting with the battery. Also, test the 12V dedicated supply for the Wifi but use it on the DSC and see if it does that any more.
