I know a lot of may think Captain America will die, because of the comics. I think he will not die for the following reason:
1: That scene in Avengers: Age of Ultron
- I gonna guess and say all the people reading has seen Age of Ultron. If so, remember that dream sequence that Tony had when he touched Loki's scepter. It looks like that fight took place in space. And I think that Captain America might die Avengers: Infinity War.
