How long does WM last as a FS?

[Warlock*G]

Just looked at a video and it lasts approximatively 17 seconds, or 20 seconds if you count the beginning and the end during which you cannot move, because Wario is transforming.

when hes wario man his aerials make him float so you can edge guard like crazy

Doesn't it go until he dies?

[FREZ]

It lasts around 20 seconds but he does turn back into Wario sooner if he dies as Wario-Man

Doesn't it go until he dies?

Nope. If it did it would be unfair. The match would be yours as soon as you'd transform into Wario-Man.
