The reason you guys give is too is unspecific, but I did research the Super Form's time limits on Super Sonic: The amount of time that a user can sustain the Super Form simply depends on how long the user himself is able to handle and manipulate the infinite pool of Chaos Energy. In Sonic's case, he has been able to sustain the Super Sonic form for several days with seemingly no issue, whereas Shadow was exhausted in Sonic Adventure 2 after using Chaos Control because it was his first time being Super and thus was not used to holding the transformation. I'd also like to point out that the enemy being faced or the attacks the Super Form receives have nothing to do with how long the Super Form lasts, and this is because the form is invulnerable, invincible and indestructible, it's simply relegated on the user's experience.
