Who is Naruto's father in Naruto? Why did he die?

Namikaze Minato, the fourth generation of Naruto, was proved by memories before Jiraiya died. Naruto's mother's name is Vortex Ai Chen, and Naruto's name is the name of the protagonist in a story (not intimate paradise) originally written by Jiraiya. The four generations used this name because they liked the protagonist's character very much. Kyubi no Youko, who was released to seal Uchibo Madara, died.
