It sounds like there may be an issue with the power amp section of your amplifier. When the distortion gets deep and saturated, it could be drawing too much current and causing the amp to shut down to protect itself. This could be due to a number of reasons, including a faulty power amplifier IC, bad solder joints, or a power supply issue.
You mentioned that you suspect the IC may be getting hot. If that's the case, it's possible that it's overheating and shutting down the amp. You may want to try cooling the IC with a small fan or heatsink to see if that helps. If it does, you may need to replace the IC or look into other cooling solutions.
It's also possible that there are bad solder joints or other issues with the power amp section that are causing the problem. If you're comfortable with electronics repair, you may want to open up the amp and take a look inside to see if there are any obvious issues. Otherwise, it may be best to take the amp to a professional for repair.
"Volume IC" do you mean an IC that is a pre-amp and controls the volume and things like tone? Or do you mean the main power amp IC, which will be on the big heat sink? If you amp uses the latter and not individual separate devices for the power amp, suspect that over the other IC. But if the amp has separate power amps for both channels, replace the IC.
