Pontiac: 1986 Pontiac Grand Prix problem

Alright, it's me again. I have found some help in here on this car that I
just purchased a couple of weeks ago, and I now have it Emission tested, and
safetied, and I am legally driving it now. Or, well I was I guess until
today on my way home from work.
I started it up and took off a little bit quicker than I have usually been
the last couple of weeks (It is quite cold where I am, London Ontario
Canada) It has seemed to need about ten minutes of idle time before taking
off, or even shifting it into any gear. If you try to take off too soon, it
would stall most times I have tried it in the past. today though it seemed
fine when I put it into reverse to back out of my parking spot, so on I
went. I drove for about probably 7 or 8 kilometers and it ran fine. I then
pulled into a gas station, turned the ignition off, filled up, (it was
pretty empty), then tried to start it up and got nothing. I mean, it turned
over and sounded like it was going to start, but just wouldn't.
I didn't have time to fiddle with it right then, so I had to call the wife
to come pick me up. While waiting for her I tried to start it a few more
times with no luck. I am not sure if it is fuel or spark or what, but it is
trying to start, but just won't. The only thing I can think of that was
different today than any other day, is that it was lower on fuel today than
I have let it go in the past, but in defense to that, it ran fine all the
way to the gas station. Also the fact that I took off right after starting
it up, but again it seemed to run fine the whole drive.
Does anyone have any knowledge on this car? It has a 305 V8 in it, with the
4 barrel carb. It is automatic.

Any help would be greatly appreciated.

Well, it's not like I'm tryin' to come off as an Eskimo or anything like
that...

Thanks for the pointers Jim, and yours too WHO??

It seems the car has some ghosts or something. That night that it would not
start back up for me after fueling it up, I could not do anything with it
because I had to have the wife come and get me and she had to go to school
and write a test, so we had to go back home (about 20Km) to drop off me and
our daughter, so my wife could then proceed to school.
So, the next morning we got up earlier than usual, and went to the car, and
of course it started right up as if nothing had happened. So daughter and I
get in it and head off to work/school, and wife heads to her work in her
car. Car has run fine since. Only thing I have noticed was that morning, my
daughter pointed out that the interior light was on. It was just dim, but it
was on. Also the passenger's side foot well was lit up too. I try the
headlight/interior light switch, and it is in the off position. ??? So I
turn it to the on position, and the footwell gets brighter, but the
dome/ceiling light goes out. hmmmm ......... ????????

turns out it is a bad fuse (20 Amp Dome fuse) So I replace it, and the light
problem is fixed. ...... Until tonight on my way home from work. I turned
the headlights on (I am not sure yet if they were actually on or not, was
just a bit gloomy out, not dark yet) After about four or five minutes, my
daughter said the light was on again. Sure enough, it was lit dimly again.
So it looks like I have a wiring/switch problem or something.

Any ideas where to begin looking?

I'll check back soon.
