Hello all,
It appears that possibly I have a dc-dc converter failing in my 2014 model S, or maybe an intermittent wiring short circuit.

Three times now in the last two weeks, while riding, the bike has lost all 12V power (dash backlight, horn, headlight, turn signals, brake light, etc) for several minutes (no flickering) and then recovered by itself. No blown (or loose) fuses on the 12V side or the high voltage DC side.

No obvious wire shorts, and no blown fuses. Possibly an intermittent short causes the DC-DC power supply to go into overcurrent protection and shut down, then re-enable later? Or an occasional break in the enable signal wire?

I hope I don't have to replace the $200 DC-DC converter part.

That's exactly what mine did.  Go ahead and replace it because it won't come back on very soon.

Interesting -- how long did it act unreliable before it died completely?

About 3 rides with each time losing the dash for longer and longer periods.  You just have to bite the bullet and get it changed out.  It's just very unsafe when it dies.  Be sure and wrap it in that aluminum tape if you do it yourself.
