I have a 87 vanagon was running fine. My wife drove it 6 blocks and turned off.

What is your question?

I went to start it 10 minutes later & it will start but dies when I give it gas and is idling very rough. I pulled fuel line & have plenty of fuel pressure at other side of filter. I let it sit overnight with battery unhooked & it started & ran fine until I turned it off. Now it is doing it again. We love the van it is the camper special and want to get it fixed soon.
