I am having the same or a similar issue. I pretty much gig every weekend, and the Pod Go has been my main rig for a while now. My last 4 or 5 gigs, I have been getting the volume fading out and then back in, or volume cutting out completely. Usually, rebooting the unit is the only thing that fixes it. Doesn't happen in my house when I am practicing. Only at the gigs, but all those gigs have been outside. It isn't just 1 patch or amp, it is all my patches. I opened a ticket with Line 6, but haven't heard back from them.
