Not trying to steer you in this direction, just making sure you're positive this isn't the issue. Also, from your version of the repair guide:
4. If no discoloration is found on the cable insulation, proceed with standard
troubleshooting to identify the voltage drop in the battery cable circuit.
I'd look around for that "standard troubleshooting" guide.

NGEE - Thanks a lot for those documents, there was lots of good info in there. I will look for that other document, but given that it is intermittent it might be tough to figure out if I can't reproduce it in the garage. I'm really starting to lean towards it being the BST->engine bay cable, but nobody else seems to have had that problem.
Thanks again.
