Assuming that you have diagnosed the failure correctly, then the most likely possibility is a locked up fuel pump. The fuel pump on this vehicle is located inside the gas tank, and it relies on being submerged in fuel for cooling and lubrication. If it is run out of fuel, then teh pump can overheat and sieze up.
Try whacking the bottom of the tank with a rubber mallot or something similiar; sometimes jarriing them can make them operational again for a while. In any case, even if this makes your vehicle start, the pump is old and probably at the end of it's life and should be replaced if it is the cause of the problem.
