It sounds like your amp might be going into protection mode, does it have an indication light on it? Either that or a hairline crack in a fuse which can get worse with the cold/vibrations.

Do you have a multimeter? I would check voltages (car on) at the battery and at the amp to be sure you have the full 13-ish volts.

One easy thing to check is where the ground for the amp is located. It would easily be cutting off any form of power if it's corroded or lose.

And I've seen a few cars before that had these symptoms, and it was caused by loose or bad RCA's behind the deck going to the amp. Again, if you have a multimeter check on the resistance of those (and obviously be sure they are tight). Check all of these and come back and I'll help the best I can.
