You might try asking on rec.audio.car.
I would try powering it from a 12v power supply and following the power
bus. Use a heat gun and gingerly heat small areas until it works, then
use a circuit cooler spray to cool it off in various areas until I could
reliably make it start and stop.
Sounds like a poorly solder connection somewhere such that the
conductors move/expand connecting when hot. That type of problem is
more common than you might think. I used to see it at times when I was
working in electronics. Especially component leads going through a
soldered connection hole in a circuit board. The connection visually
looked fine but when moved with an insulated tool or heated and cooled
as I described would fail.
