Disabled Radio

[Max Hoepli]

I left the car standing 5 hours until I started the car and the radio was
not disabled. When I leave the car standing for a longer time the radio
becomes disabled.

I would add, measure voltage at various places during that starting 
phase.  An analog meter would probably be easier to read for this.

Steve is almost certainly correct, of course - at one phase of the 
starting cycle, the voltage to the radio is dropping too low.  It could 
be a ground lift or a positive drop or a combination of both.
