The newer vans have a feature that if the VIN# in the various computers don't match, the engine control model assumes the vehicle has been stolen or altered or there is a major malfunction and the engine is immediately shut off. Since your gauges are not working correctly, I would assume that one of the modules are not reporting the VIN # and triggering the shutdown, probably the one that controls the gauges. That is where I would start for a solution. I think it is the Body Control Module that is responsible for the gauges, but I'm not sure.
