Could possibly be a crook protection circuit in a battery pack - I have one here that the cells all check out when individually tested and everything works right but with a bit of load on it the thing shuts of and the tool stops. Plug it into charge, and the charger says fully charged. Seems to work OK on light drains like a torch or a drill using a small drill, but on grinders or circ or recipro saws it shuts off virtually straight away.
