Narrative:

On final [approach]; my engine started running rough and felt like it was going to stop. I was a few hundred (100-250) ft from the threshold. I pushed the throttle in half; hit the fuel pump low boost; then the starter. The engine reengaged and came to power nearly the same time the mains hit the ground. I bounced very high. I cut the power; and then increased power to get the airplane under control. At that point I was just glad to have the plane safely on the ground. I should have notified the tower; but I was disorientated for a few seconds and turned right onto [the parallel runway] instead of left. Tower had apparently given takeoff clearance to a commercial flight on [the parallel runway] and had to stop that takeoff. I taxied to [the ramp] and the engine quit about 30 ft from the tie down. I have scheduled to have the apparent fuel problem and/or engine issue fixed by my local maintenance shop.
