We don't know. Sure at some point he'll die, but the actual circumstances? For that matter, will Kawaki be the source? The series right now is just Boruto reminiscing about the past and he says his father is only a small part of that story, near the beginning.

Secondly, it wasn't like the Hokage interfered all the time in Naruto's missions. It's perfectly doable for Boruto to go on missions and encounter powerful enemies without Sasuke or Naruto showing up to save his ass all the time. Especially since the Otsutsuki are apparently still a real threat (meaning Sasuke will likely spend little time in our dimension, and Naruto will be coordinating in stead of spending time on the front line).

Then there's the fact that Kawaki's words are suspiciously exact, so there's plenty of reason to believe that Kawaki simply sent him to another dimension, forcing Sasuke to go after him and leaving Kawaki to Boruto.

All in all, we simply don't know. Considering how huge his name is, i don't think anyone will be terribly keen to kill of Naruto at any point.
