Agree with likely bad fuel pump. At your vehicle age it's due. When it cools down the pump will work until it heats up again. Intank pumps can be limped along if you keep the tank above half way (emergency short trip only). You have been changing the filter on a regular basis? If the filter has been plugged by stuff or water it can also help the pump to overheat to early failure.
I have seen a Ford Fuel injected 460 Vapor lock. The guy used Arco gas. The higher alcohol content combined with high ambient temp and high altitude caused vapor lock while offroad. We removed the hood of the truck. What finally sorta fixed the problem was placing ice from our lunch coolers into sandwich bags and zip tie the bags to the fuel lines. Repeat every half hour.
