I would check the flywheel key and see if it has sheared. On push mowers, the key can shear if you plug the deck, or if you hit a solid object like a tree root or stake. The flywheel key sets the ignition timing of the engine, and a sheared one will cause the problems you describe. You will have to remove the shroud and flywheel to check the key. If you don't know how to do this, there should be some basic repair manuals at your local library or online.
