I have a 98 chevy venture that did the exact same thing, and it drove me crazy when I knew the fuel pump was still good, and I traced the wire and plug in connector along the drivers side mounted on the frame just underneath the drivers side seat and found that the plug connection which also runs the fuel gauge was nasty, wet, and corroded, I unplugged it and squirted some backing soda several times up in the prongs [and flushed it with straight water], and took a small piece of wood fingernail file and ran it up and down all the prongs, and the van starts great again and fuel gauge does not fluctuate. There is a name for this wire connector but I can't remember it but advanced auto parts, or any other place would propably know, if you show them. After I cleaned it up I let it dry good and wrapped it up in electrical tape as these vans rust very badly along the lower kick side panels and take on alot of splashing water and winter salt. Try this and you will propably find your problem. Hopefully, but I'm glad I checked as it cost me 10 cents worth of good electrical tape. AMEN.
