When I start my van, it dies right backout. on 1994 Ford Aerostar

What could make my van die right back out when I start it up?

You need to check and see what is going away when it dies, are you losing spark or fuel pressure? Have qualified tech check to help and go from there. You could still have both and it starts right back up and now you need to look for large vacuum leak, cel codes, etc.
