Hello Alex!
as you describe your problem it looks like something wrong in the analog output circuit: dry solder joint, bad contact or some "ill" op amp or transistor that goes out when hot. The heat related failure is probable because it works well for a short time and after the sound decreases, a contact problem would occur more irregularly. I'm not at home currently, so i cannot open mine to tell you what to look and where. I don't think it is a fatal issue at all, but it could take a long time to find the faulty part.
You can try 2 things without opening the synth:
First remove all additional devices (effects, patch bay..) between the AN1x and the amp or mixer.
Then turn on your synth with the line out plugged only,play it,
and after do the same thing without line out but with headphones only.
If you're using a mixer try another input with the line out connected.
Look (or more likely hear !) if there is some difference....
Cheers
