Thanks Tim!

She made it to her next stop after letting it sit for a few minutes and said it didn't miss a beat for the rest of the three hour journey. At least she wasn't stranded somewhere!

I'll be sure to look into the areas you recommended. As far as the original post goes, the van never threw any codes whatsoever.

Hmmmm...you know what...I did replace the fuel filler neck in December and they sent the wrong part and it was too short so I bought some fuel line (NOT CHEAP!!!) to use as an extension from the tank to the filler neck...could that cause either some kind of vacuum or pressure leak if one of the clamps has come loose or something?
