Hello. The symptoms you describe can be caused by many things. If your vapor canister is having known issues then I would start there, as the vapor canister is tied into the vehicle’s fuel system and can affect its performance. It may be possible that the canister is compromising the fuel system and needs to be replaced. It may also be possible that there is some other issue with the fuel system, such as with the fuel pump or carburetor, as these are the components that deliver the fuel to the engine. Stalling and no start symptoms can also be caused by a wide variety of issues, such as problems with the ignition system, electrical problems, or other issues such as vacuum leaks or electrical problems. If you are also having a problem filling the vehicle that may also indicate that there is an issue with the filler neck, which may warrant replacement of the tank or neck. As it appears that your vehicle is experiencing more than one issue, I would recommend having a professional technician, such as one from YourMechanic, visit your location to diagnose what may be causing your stalling..
