Welcome to FTE!
I have heard of this problem before in the Crown Victorias with cruise control. It seems a faulty solenoid valve was allowing a small amount of vacuum to be applied to the cruise control actuator. If the van has cruise control, try disconnecting and pluigging the cruise control vacuum line.
