It is very simple to determine if it is a fuel or ignition problem. First remove the air cleaner and observe if the accelerator pump is working by actuating the accelerator linkage and looking down the throat . When you encounter the problem on the road observe again. If it does not work then the fuel bowl is empty and you have a fuel supply problem.
I would check the fuel pump sediment bowl for fine rust particles which clog the brass screen and after you rest a while fall to the bottom. Had that problem in 1966 with my 1940 Henney hearse.

Ignition. With engine cold, crank it with the coil wire removed from the center of the cap and hold it 1/4" from something metal. Observe the spark. When the car fails on the road repeat, if the spark is still fine then ignition is OK, if the spark is very weak or not there then the ignition is the problem.

Repairing by replacing on thing after another is no an efficient way to fix something, proper diagnosis is necessary.
