The thing about running out of chakra is that, it eventually comes back. Had Naruto permenantly run out of chakra, he wouldn't have been able to help Sasuke deactivate the Infinite Tsukuyomi. Hell Kurama used up all of its chakra to give Naruto one final boost of power, and all it did was put him to sleep.

I don't believe Naruto could just "run out" of it forever. Spend so much that he can't use any more for a while, of course. Run out completely, I don't believe so.
