Intermittent idle & stall

[WBITTRICH <WBITTRICH@aol.com>]

A friend of mine has an 84 5000S that has developed a problem.  At start up it
idles well and normal, but once it warms up a bit it begins to cut out.  It
then comes back before the engine dies completely.  It does this out and back
at about 1.5 second intervals.  There is no apparent affect while driving,
this is only at idle.

Is it a fuel issue?  Maybe the idle control?  I'm going to do some diagnostics
today, but I'm sure I am apt to miss something, which will certainly be the
problem.

Anyone out there on the planet have any clues for what it might be?

Thanks,
