Problem:

The 93SV at the console either shuts itself off, reboots, or locks when I press any presets (preset 1 is navigation, preset 2 is 2D and ClearVu). 

Configuration:
UHD 93SV at console (flush mount)
Ultra 106SV at bow
Livescope GLS10
All three of these units are supplied with 10AWG marine wiring through an “intelligent” fuse panel

Attempted Solutions:

1. Replaced network cable – no fix
2. Replaced 93SV with an old Plus 93SV – problem did not occur.
3. Garmin sent remanufactured UHD 93SV – problem recurred
4. Replaced 93SV cradle – no fix

Notes:

Problem does not manifest if the units are NOT networked.
Problem does not seem to be heat – happens even on cold days no air restriction under console.

I found the solution in case anyone else has run into this. I did not mention that the Force Trolling Motor has a transducer built-in. That transducer was plugged into the 106SV and the transom mount transducer was plugged into the 93SV at the console. I had an old Plus 93SV which I mounted at the bow, but did NOT network. I DID attach the transducer from the Force to the Plus unit (again, not on the network) and there are no problems.

Glad you had the mental fortitude to figure it out. I'm not sure I could have figured it out. Good luck!
