Actually in the end Naruto pretty much has to die or loose his powers (not all of them) cause he would be way to overpowered... no one would be able to face him and with him being an Uzumaki, he would rule for quite some time.
About him dying by having the kiuby extracted... well No just no... it's stupid. His mom survived (and i have said this somewhere else: she survived after giving birth, struggling to also keep the nine tails inside, and after she had the kiuby extracted she wasn't even in a come state or anything like that, furthermore she was even able to use her chakra chains to restrain the kiuby later on) and Naruto is her son so i am pretty sure he would survive the extraction itself, even though he would be weakened.
And about him dying overall well it won't happen (if it happens) until the end... he might die and be revived along the way, can't say for sure.
