It wasn't the voltage.
I'm happy to report that my XPB is running and thought I should send an update. I installed a new Facet fuel pump. I ran it a long time before I got fuel at the secondary filter bleed screw. She started, ran for 30-60 seconds, and died. I pulled the fuel tank take-up tube. It had both the hose and screen at its end. The screen was dirty, but I couldn't say it was clogged. I removed the screen and ran the fuel pump more, without bringing fuel to bleed screw. I conferred with our local marina diesel mechanic and we agreed I had either or both a restriction or leak in my fuel delivery system. So, (to use the transition now favored by all the media) I replaced all of my fuel feed lines and removed the original Facet fuel pump which was still in-line but not operating. The old Facet pump screen was fully clogged. And, I found cracks in my fuel line that I may have made worse changing the pump.
I ran the pump and fuel quickly gushed from the bleed screw. The whole system sounded like it was breathing or gulping more deeply than before. She fired right up and has now run without a hitch for several hours. I may be misled by the glory of fixing my problem, but I think she's also running better at lower rpm's.
Thanks for everyone's help. Through this process, I've learned a lot more about my XPB. Now, it's time to head to the North Channel!
