Weirdo electrical problem

I've run into a weird electrical problem (aren't they all, though?).

I have a '78 B - the other day while driving my stereo cut out for a second 
then came back on.  It happened once or twice thereafter.  I figured I just 
had a loose wire.

What happened today is that once the stereo cut out, it'd STAY out, and 
further, would not come back on until I shut off the engine and restarted 
it.  Generally this was after going into a store or something so it sat for 
a while - I'll have to see if I immediately stop and restart if it makes a 
difference.  Also, once I restart, it's generally on for anywhere from 10 
seconds to a minute before it'll go off.

I then noticed that when the stereo is off, so are the following:

- Horn doesn't work
- Cigarette lighter socket has no power
- Convenience interior light (that little one about the heater controls) is off

Further, the turn signal is acting weird - it stays on longer than usual 
then will speed up, but is never quite at the normal speed.

Finally, though I will test tomorrow - the temp gauge got REAL high - 
touching the red - while sitting in traffic, leading me to suspect the 
radiator fan wasn't kicking in, but I wasn't in a position to check just yet.

I know there's a sort of incestuous relationship between the horn, cig 
lighter, and interior lights - I think they're on the same quasi-circuit - 
and I know a bad turn signal relay can do weird things, but can it affect 
the others?

Things that seem unaffected:
Headlights
Dashboard/Instrument lights
Overdrive switch (it's electric)
Wipers

If the things that were broken were always dead, I'd just go looking for a 
short, but because it all works for the first 10 to 60 seconds, then it 
dies, I'm suspecting an electrical component is flaking out, but don't know 
who the culprit might be.  In the morning, after it sits all night, I'll 
see if it stays on for more than 60 seconds.  In the meantime, I'm hoping 
maybe someone here with a better understanding of All Things Lucas would be 
able to point me in the right direction.

Thanks
