If that's a Holley carburetor, there will be plugs on the sides of the float bowls for viewing the fuel level. When it stalls, pop one of them out to see if the level is visible. If it is not and you have a mechanical pump on the engine, suspect a plugged or collapsed pickup screen in the tank.
If fuel level is ok, check for spark right after the engine dies. Since it takes a few seconds to die, a typical electrical cause would be a defective ignition coil, or less likely, a shorted condenser.
Check the battery voltage while the engine is idling. It must be between 13.75 and 14.75 volts. If it is low, the battery will not fully recharge and an electric fuel pump could stop working.
