Yes, this was an outdoor show next to the river. Low humidity, cool evening.

I had a VMS02ib fade out on me once but it was both channels and definitely a battery issue and it took about 5 minutes for the audio to get to almost 0.

The power is shared all the way up to the Y junction in the KCY - so it's either a problem in the KCY Collete or the SAX IMO - My guess would be with the SAX due to the simplicity of the KCY

Could be a power issue with the FET in one Collete having a wider voltage tolerance.

Is it working ok now?

I ran the same setup tonight for an hour long set without any problems.

Could be a failing Capacitor (where environment may cause the issue to arrise more heavily)

Could still be a power issue - I have found that over time the battery gauges on Tekkeon, Battery Geeks, etc becomes less reliable due to Lithium Cell age.

Cracked trace leading into capacitor? Also would check solder point at capacitor. bigger ones can stress through holes.
Environment related intermittent.
gradual discharge of current during failure.

Still - wouldn't all those potential problems affect BOTH channels, and not just one of them?

Not necessarily - nothing is perfectly matched and /or if something is starting fail it may only affect one channel's components

That's what I thought first, but then other's arguments led me to think the other way.

Anyway, the OP has recorded another show without problems:

Same settings & battery? Indoor, outdoor, cold, hot?

Same settings and battery. Outdoors again next to the river.

Funny thing - early yesterday morning I was tracking out a show I recorded late last week. So as to not disturb anyone, I listened using earbuds plugged into my computer speakers.

While listening to various pars of the show, I suddenly heard the right channel slowly fade out and disappear. My first reaction was to think the recording was messed up. Turns out, once I reinserted the connector plug (3.5mm), everything was fine.

Maybe the op just had a dirty cable connection.
