    disconnect the solar charger, run the lights or t&t for a little bit and then measure the battery voltage. then start the motor and see what the battery voltage reads while the motor is running, if it is not higher than before you have problem with the system charging system

    Hard start when warmed up

    not sure about the zuks, but some motors have a fuel cooler and if that does not cool things properly the gas in the VST can boil out shoving all of the vapors into the intake causing too rich envirment during restart
