A quick way to diagnose the problem is to turn your transmit
power down temporarily.? I've also seen that FT-857's are much
more sensitive to RF around the radio, whether it comes from
cables or coming down the coax.? The classic symptom is just what
you describe--power cycles off, then on again.
It's possible that something very minor changed on your antenna
system to cause this.? It wouldn't even need to be a very
noticeable change.? A likely second cause could be a power supply
issue, but my bet is on RF around the radio, though.
Good luck.? Been there, done that!

The FT-857 radios are notorious for RFI issues. Make sure you have
plenty of ferrites and good grounding. You should probably be
using premium cables.
Gaston, the Techprepper on Youtube I believe found some
shorter better shielded cables for connecting digirig to an
FT-857, if you aren't rolling your own.

Setup was working fine. Then
it started failing. With FT8 on WSJTX or Winlink - at
some point (I think on end of transmit) the radio would
turn off and on again - sometimes repeatedly...
I tried it on two different computers (and RPi and a
Windows machine) that had both been recently working
(FT8 on 15M was great to Europe from California earlier
this week)
"I didn't change a thing" - but perhaps there is some
radio setting? or a failure in either the radio or the
digirig?
Suspecting RFI - I reset all of the antenna connectors -
switched battery - reset all digirig connectors.
