I filled my 1986 Astro Van up with gas, drove for about two hours when it just died. I pulled over to the side of the highway, tried restarting it and nothing. I had a person try and boost it, nothing, was told maybe vapor lock, so I open the gas tank, still nothing. Fuel pump is working. So what could cause the van to just stop running? Any suggestions would be greatly appreciated.

If its l986 it doesn't owe anyone a thing so give it a decent burial.

My bet is that the Ignition Control Module is bad.
