how can he run out of chakra? since hes on sage mode.. he get infinite power.. and we dont have to count the nine tails beast chakra...
he can run out of normal chakra

Sage powers take a mix of normal chakra and sage, so that means that less normal chakra he has the less sage he can use w/o turning into a toad.
Not sure if kyuubi power could be used with sage power.
Even if kakashi wasn't dead before, he didn't have a slug on him when the big explosion happened. kakashi is dead, and both naruto and tsunade know it.
