Astro van turns over then stalls right away

What is your question?

Van sat for almost two months was able to drive it for 2 weeks then one day it turned over and then stalled .. have checked fuel pump with a pressure gauge, changed the fuel filter, distributor and rotors and sensor. Looked for leaks in vacuum and fuel lines... found nothing.. Checked codes using three different readers, none come up.. have tried the security pass lock test.. the security light is out. So what else could it be!? Help!!

What makes this problem better or worse?
