You don't give us much info to start with but here is an idea.
It sounds like it is starving for fuel. Is the fuel supply from a separate tank or from the van's tank? If from the van tank is it a separate fitting or does it come off the van line? Most modern vehicle engines have the fuel pump in the fuel tank so the line is under pressure. When your van was running the generator ran fine because of a constant supply of fuel. When you shut off the van the pressure goes to zero and the generator cannot suck enough fuel from the tank and dies.
If this is the case there are two different possible solutions. 1. change the fuel supply line. 2. energize the fuel pump relay so that you have fuel pressure.
If it is a separate supply this does not apply.
