As vehicles age, diagnosing false activation with ABS and stability control systems has become more common. Since many are having the problem, there must be a weak link in the connections for the video circuit or control circuit somewhere. When the ignition switch is turned to the start position, the electrical power gets sent from the switch to the starter relay. While replacing the fuse, of course also visually inspect the contacts inside the fuseholder, as indeed even the smallest amount of corrosion or other contaminant present at the contacts can also lead to erratic behavior including sporadic loss of power under certain circumstances and/or total loss of power altogether. It doesn't shut off and blink any codes to go by. While power stays out, no heat can be generated, so there is no fire hazard at all then.

(There's an outside chance that one leg of the circuit is still off, which can cause super-weird stuff to happen.) Diagnosing something like no sound from speakers is a more complicated issue, but it involves checking the integrity of all the speaker wires and the functionality of each individual speaker to rule each one out in turn. It does not restart unless the battery is allowed to drain completely and then jump start. Check Fuse #12 (7.5A) in the under-hood fuse box. A new fuse may restore power temporarily but, unless the underlying cause of the circuit overload is found and corrected, the fuse won't last and will likely blow again. 2.
