Minato has not demonstrated the ability to seal away abilities. He's demonstrated the ability to sever one's control over/contract with a Summoning.
Building up Izanami (recording) doesn't stop one from using Susano'o. It's only after the user lands it on the opponent and thus loses an eye, that Susano'o cannot be used.
Genjutsu isn't instantaneous, but it doesn't take seconds either. Seems to be nearly instantaneous once you get eye-contact.
Which is why I won't use them in a battle situation. I'm playing fair. Plus, could you imagine 5 Minato's teleporting instantly around you? With Rasengan's? But, I won't even present that since he hasn't done it.
No he can't seal away abilities, but he can move/teleport chakra (AKA beast ball). I don't find it that big of stretch to say he can't temporarily get rid of a chakra based defense like susano'o. Long enough to attack anyways.
As far as Izanami, I inferred from the fact that Itachi had on susano in one frame, and then when making the seal to activate it, susano was gone, allowing Kabuto (who is much slower than lightning by the way) to split him in half. Had he not had the resurrection effect he would have died. If Kabuto could tag him, Minato could tag him
