The newer models will quit if the battery voltage falls below about 10 volts - the alternator will not power the machine if the battery is dead and it's possible the charging system failed because the battery was weak. The charging system is not designed to charge, but to maintain a charge. Run the engine below 2500 RPM and use high current draw electrical accessories and the battery will go dead while running. Also, if the battery is completely dead and will not accept a charge or is disconnected while the engine is running, it is possible to burn out other components due to electrical surge. When the battery is completely dead, do not jump start the vehicle - charge or replace the battery before starting
