My baby, an 87 Charvel Model 5 has stopped talking to me. Was playing thru JCM 900 and it just quit...no loud squeal, fade of sound, nothing. Here one second and then silence.

She was professionally moded with Seymour Duncan HBs about 5 years ago...the mid boost removed, new wiring harness and all...never gave a lick of trouble.
It's the guitar, because I plugged others into same cable and amp and they're all fine. Tried different pickups, nothing. Tweaked volume and tone controls, nothing. Never had this happen or heard of it happening.

Any ideas?

ETA: I tried my old solid state Marshall head, different cables, bypassed effects loop with direct input to head...nothing.
...and I've never dropped her.

Probably volume pot went bad/shorted. Bring it to a tech. Bet it's nothing.

I hope that's all it is.
Just to go dead though...no crackles or anything...just bizarre.

My first guess before a pot or cap crapping out is a solder joint somehow came loose in the cavity. On a jack, on a pot, etc. Your description of before/after fits - one second, just fine and then pfft, dead. Might have been a cold or inadequate solder joint that finally worked its way loose. If that's the case, that's a breeze of a fix.

Time to replace it with a good ol' Series 10 guitar, hossfly.

First inspect all the wires carefully for tiny nicks - doesn't take much to make a short.

Then try jumping the pickup leads straight to the tip of a cable - just for a second, to see if it makes noise. If they work, it's probably a busted pot. Easy & cheap fix.

That or the cord jack, I had one of those go out the other day on one of my tellys, it didn't make a sound either.

I had something similar happen a couple weeks ago on a brand new guitar. It cost me $90 with tax to replace the jack and 3-way electro socket. The seller split the cost with me.

Care to share a few focused, large photos of the cavity from multiple angles? Remove the three screws securing the Model 5's control plate, you won't hurt anything removing that plate. I won't be able to see the inside of pots and stuff like that, and the jack's solder contact points may not be visible, but I can look for obviously detached hots within the circuit.

I've read the OP several times, and I'm still leaning towards a compromised contact point in the "hot" path of the circuit due to a failed solder joint. The hot out off the selector switch; hot in or hot out on a master volume or between two volumes for each pickup; or the hot to the jack is my guess. It could very well be a component failure but pots, jacks and switches tend to give warning signs prior to crapping out.
