Do doc...
When the engine dies you can pump the accelerator and see the accelerator pump squirt fuel into the venturi?
After it dies have you checked for spark?
If it is fuel related you could take some starter fluid and it should fire up.
You should also remove the fuel filler cap right after it dies and see if there is a air rushing sound.
If it is electrical ( what I suspect) things have to cool down to work again. Had a pinto that did that.
