DC-5 cutting out.....

[Lankyleo]

picked up a DC-5 combo about a year ago, and shortly there after re-tubed it with JJ's from eurotubes. Past few times i've fired her up she'll be fine for a while then after about 30 minutes or so the volume will cut out heavily, to where the amp is just whisper quite, and then come in and out randomly. I swapped tubes, cords, guitars, and everything else that can be done easily and problem still persists. As the issue comes and goes randomly trouble shooting can be a pain.

Any suggestions on what it can be/what to check out would be appreciated.

Don't know if you solve it?
IF NOT,you can try to roll the FX MIX pot to min.
