If you take your foot off the accelerator pedal and the engine dies right away, that's not a battery or alternator issue. That sounds much more like a fuel or air issue. If an engine can't idle on it's own, try looking at the intake air control valve. Of course this opinion is based on limited info, if it is indeed an electrical issue, make sure to have the alternator load tested and ensure voltage regulator is working.
