Naruto isn't allowed sage mode.

He still has Kurama's Chakra mode, Six Path sage mode. (you said Sage mode alone.) He can win easily. He has speed and strength on his side, not to mention his ability to trick his opponent. Naruto would win, Hiruzen's reaper death seal may be an option, but Kurama would recognize the jutsu, plus Naruto in Six-path sage mode, or Kurama mode might be able to sense the jutsu.

Before you say labeling Sage-mode includes Six-path sage mode. The two are different, but even if you edit the rules and include it, Kurama Chakra mode is still an option.

Naruto wins.
