Two days ago I discovered that the failures had indeed totally trashed
the system.  I did re-install, formatting only / and /boot, but I've
had a couple of these spontaneous shutdowns since then, which is why I
suspected hardware failure.

I've got copies of just about everything, I think, on an external
drive, and I could try another drive as you suggest, mounting the old
one in an external case, which I have.  I can cope with this, but I'm
deeply unhappy about not knowing what happened, and whether it is
likely to happen again.
