    One more thing to check is the rubber fuel line between the tank and the hard line going forward. They will age and crack and allow air to be sucked in there by reducing ability to pull fuel. It's worth a slide under there to take a look.

      I haven't seen it mentioned, but do you have an in-line fuel filter? If old it can cause fuel starvation at speed but operate normally at idle or until the fuel in the float bowl of the carburetor is used up. Remove it or replace it for troubleshooting.

        We had a very similar problem on a race car. It ran great until we got on the track. After about 3/4 of a lap it would die. I would coast back into the pits where it would start and run fine. Finally found a soft fuel line that was collapsing under negative pressure. As soon as the fuel in the filter and carb was used up, no more fuel.
