It could be temp II as others are suggesting and you should start
there.  However it could also be valve adjustment.  When the van is cold
the oil pressure is around 60 psi at idle.  If your valve adjustment is
too tight it can make you have low manifold pressure at idle which can
lead to running like crap/stalling.  You can check this with a vacuum
gauge in a minute.  You want to see around 15 inmg at idle.  If you are
seeing less then you should probably let the van heat up, check it again
and then adjust the valves to zero lash all around and see if this
brings your manifold pressure up.

Hope this helps,
