There's already a similar question but unanswered, and it happened differently:
3 days ago it was fine, I was driving and it shut down, then turned on again almost instantly. It happened twice. The 3rd time was last night, but this time it never turned on again. Volume was not so high, and I already checked the car fuses, except the stereo's fuse [the one at the back of the unit] and they are fine I think. And this happened only after I got an amplified subwoofer installed. It draws power straight from the car's battery, not from the stereo.
Car: Honda Civic 98
Stereo: Kenwood I-don't-remember-the-model but with USB
Sub: Amplified Bazooka
