With PPOB being active, the truck is in a running state, therefore the DC/DC inverter to replenish the 12v LVB should operate as needed.
I think the key word here is ‘should’.

I just spent the last 3hours either driving or setting with my truck running and the moment I pulled back in the garage and shut off the truck I got the dreaded Deep Sleep / you have been disconnected message.

I had periodically over the past several weeks been receiving the - You have a Vampire onboard and if not you should schedule an appointment for service.
( My message interpretation.)

This has become Very disheartening!

If you keep getting the vampire onboard message, PM Ford support. They monitor this forum and are very helpful to coordinate service between engineering and the dealer. If you just go to the dealer, good luck
