Yes...I believe he can only use it in a quick burst for one attack. As I don't see any reason for him to not be without it afterwards. Maybe it has something to do with his arms? Idk... I believe he can only use it for about 10-15 seconds or so.

Come on guys, be real here. Minato is a ' PERFECT SAGE"! There is no way he can only use it for a few seconds. Being a perfect sage means he's mastered senjutsu.
Or he noticed it was useless after he tripped like Hinata.
I'm sure that if Minato really did have a limit, it would be minutes and not second.Well....idk I was just saying how I felt I was asking about it a while ago how it went away so quickly. Iirc....wasn't Naruto on a time limit with how long he could keep it up? Not sure on it though....wasn't it 5 minutes or something? Come to think of it, it seems he wasn't able to keep his "BM" up for that long as well. Or at least it went away quickly I think. Idk... why do you think it went away? I was just going by what I saw in the Manga. >_O

I see....cool, but I still feel the same just saying.![]()
He lost an arm, it probably went off. Not like there's any reason to keep it on.
Nawl he realized it was only so little he could do with No arms so he released the chakra
I mostly agree with what your saying. I never thought one could get out of Sage Mode by choice, or that they had to keep gaining Natural energy as they fought.I don't think you can force natural energy out of your body, otherwise, chakra reserves wouldn't be an issue for senjutsu training.

The only thing is that I don't believe we would be able to say how long he can hold it since we didn't see him get out of it.
