Omnipotence is all-powerful. Omniscience is all-knowing. So no, that doesn't follow.

If God knows whether or not Sam will be hit by a bus tomorrow, then He is powerless to change it. Hence, it cannot be omnipotent.

If God has the ability to stop Sam from being bit by a bus (or to cause a bus to hit Sam), then He could not have known what was going to happen before hand. Hence, He is not all-knowing.
