Voltage problems, cutting out when hot

The 5.90 and the 10.19 volt are measurements taken from either side of the MSD .8ohm ballast with the key in the on position, engine not running.
The two pictures that follow are being taken from the 5.0ohm side of the factory 4 pin ballast in the same manner, key on engine off.
And yes, one of my main concerns is in fact why (or where/what) is the VR getting the wrong information...
Thank you for the well laid out explanation and graphs.
