4kq start problems

[Barbera <barbera@twd.net>]

I have an '86 4kq with a start problem.  When you first turn the key,
the car starts, and then stalls right away.  If you don't keep it from
stalling after the first start, it won't start at all.  You have to wait
another hour or two, then it will do the same thing over again.  When
the car is running, it idles rough.  Does anyone have any suggestions? 
Is it possible I have vapor lock?  If so, what would cause that?  Any
suggestions would be appreciated.  Thanks
