Sure, check your relays, typically mounted right above the driver side wheel well on your van. It probably has some corrosion built up inside, and the amps are too high to work properly. The same problem happened to my Chevy S10 pickup. The Fuel pump relay was the problem.

Mark D sound good on this, An electrical short usually blows fuses immediatly. A diagnostic will point you in the direction, but usually will not pin-point the problem, It will give you a start, and a direction though. It may also be in your transmission( the tcc solonoid may be shorted, when it recieves the signal to activate, it blows the fuse). hope this helps.

Sounds like a short to ground on that circuit .Take it to an auto electric shop and pony up the cash for a diagnostic.This type of job is not for your average do it your selfer.
