This has occurred to me also a few times, can't say I ever noticed it
while getting a call.

Yes, very similar symptoms, although I have noticed similar issue
whenever I do flash a new distro to NAND (regardless of distro). The
first power on/boot attempt appears as if the FR is dead, until I
remove and reinstall the battery. Usually I have to wait 15 sec or so
before I reinsert the battery. I am using Qi, and I get the familiar
led flash and vibrate but then dead, but t not sur if Qi has anything
to do with these symptoms.

Mine is a buzzfixed GTA02A5 first group purchase into Australia. It
experienced these symptoms prior to buzzfix also.
I'm currently running V24 and so far have not experienced it dying
while booted, but then I have not had v24 that long. At this point I
do not feel it is distro related and suspect that it may be kernel
version related and specifically related to detecting usb cable and
charging state and perhaps even the battery meter showing invalid
state while battery is in fact quite drained. As you suggested, it
sometimes even occurs while the FR is plugged in, however I wonder if
sometimes it simply looks like it is fully charged while it actually
has a critical low battery and shuts off.

As you say, hit has not happened enough times to be able to be
definitive about the conditions and establish a pattern.
