When a car stereo cuts out and then turns back on: The problem is usually in the wiring. If the display shuts off at the same time the music cuts out, then the unit is probably losing power. Tracking down the fault can be difficult when the radio is functioning since it actually has power at that time.
If the sound keeps cutting on and off or if there is an interruption in sound while driving, this could be an indication that there is a short in the speaker wires or a loose connection in the installation. It is recommended that a qualified professional installer inspect the speaker wires and installation.
