Superman stops breathing at this point and has his heart jump-started. Meanwhile, Doomsday utterly pwns Martian Manhunter in one page. Then:

PR, it seems as if either DD was getting weaker since Superman mentioned that fear and pain affects his strength OR DD had already gotten weaker from the pain and fear he felt after the kryptonite exposure. Maybe Superman's words made him fear more. So I think it's writer's intention that he was getting (or gotten weaker) from the pain the kryptonite gave him and or from Superman's words. But definitely something was happening to DD's power level as it was mentioned.
Note: IMO, The kryptonite only made him weaker when he was trapped. After getting out and leaving, the kryptonite didn't affect him directly anymore, just indirectly (remembering the pain and causing fear in him).
