JVC KD-SX990 Stereo randomly off and on
If you've confirmed that it's actually losing power (a CD will start over when the display and sound come back) instead of just the display cutting out, then you should first check your fuse panel in the vehicle, and make sure the fuse that provides power to your radio is seated firmly and securely. Try jiggling it if you can and see if the radio cuts out then. If it seems fine, take the radio out of the dash but leave it connected. While it's powered on and playing, jiggle the connector that's plugged into the back of it. If it's still fine, do the same thing with the wiring harness that's connected to the factory wiring. At one of those connection points (fuse panel, connector at rear of radio, or connection to the factory wiring in dash) you may have a loose connection.
If you cannot repeat the radio failure by doing this, you likely have an internal problem, such as a failing power supply, or it's overheating and shutting itself off.
