It really just depends on if Tsunade and her regeneration can take more than the Raikage can dish out. If the Raikage gets tired and starts getting sloppy before Tsunade stops regenerating... Well, she is a Sannin. People underestimate her. She'd find a way.

But it is 50/50 (imo) on whether or not Tsunade can outlast him. They both have lots of chakra.
