Flash's hardest punch was the IMP, and he put all that energy he had built into that one shot. Punching someone like that is a massive transference of kinetic energy, so it'd get Superman moving again [assume he's been kinetic drained].
The fact also remains that infinite mass punch, hit a guy into orbit, but Superman can literally stand ground and bang toe to toe with guys with that kind of power. Shit, that's a good chunk of his rogues gallery.
It might sound off, because there's evidence Wally can think fast, but Superman will outthink him in a battle, despite being older and wiser than say- Bart, Wally is still act first, think after.
However, Wally could possibly do what he did to Inertia? Just maybe. Superman has actively resisted molecular time statis though, which would work similarly to a kinetic drain/kinetic stop of this sort.
