Hi,

it could be that the Charge IC is defective or the batterie has broken Cells.
This will cause the apprupt shutdown.

You can try to reset the Charge IC, remove the AC Adapter and press for more the 1 min. the powerbutton, connect AC Adapter and turn it on again charge batterie full and let it run down and see whats happen.
