Minato can teleport the susanoo away with his FTG. Sasuke lose regardless, the susanoo is not important against
Minato, and it's not like if he can hit Minato with that susanoo, not to mention it feat-less anyway.
He's not teleporting anything away when Enton can cover the Susanoo, and when Enton will kill him if he comes close, forcing him to teleport away.
...It has an Enton Orb, meaning it practically has access to everything that has been shown with the Enton Orb via Sasuke's EMS Final Susanoo.
How's that going to hit Minato?
Add the fact he can't keep it up long either, I don't see Sasuke winning this.
He can keep it up long enough, stamina is not going to be a major factor here, especially when this is Sasuke we are talking about, not Itachi.
This is an enclosed space (Kage Summit, hence where Ay fought Sasuke or where Mei fought Sasuke, either way, enclosed space), Enton Magatama (Or something similar) spam will light the area on fire with relative ease, limiting his movements, trapping him like a rat and then he falls.
