In Iceman's case, it would be a draw, because he'd have to stay there to keep Doomsday frozen, by convection, Doomsday would eventually thaw out.
Iceman can't "steal KE" in the sense that Flash does, cutting a person off from motion... he just, literally, makes them cold. But so long as there's motion in the universe, there would theoretically be something to warm Doomsday up.
The other problem is that Doomsday seems to generate his own energy. For example, thrown into the vacuum of space with heat bleeding off his person, he never froze up and never lost consciousness. That means he was generating his own heat to counteract the vacuum. So unless Bobby commits his life to keeping Doomsday in a freeze, Doomsday would eventually thaw himself out.
My take on the battle, assuming Bobby fighting at his peak potential which he rarely does, Bobby is able to kill Doomsday repeatedly until Doomsday develops immunity to Bobby's power. Then Bobby contains and exiles Doomsday to space, not killing him, but a technical ring out... eventually Doomsday makes his way back, though, and is too much for Iceman to stop.
Two most likely mechanism for Doomsday to evolve in order to stop Bobby would be either an anti-mutant ability, taking way Bobby's powers, or some form a psychic attack to hurt his mind.
