I departed with 40 gallons of fuel. One hour and thirty minutes in flight I was cleared to land on Runway XXL at [my destination]. On downwind engine started missing. I notified Tower of engine missing; would prefer Runway XR. Tower asked if it was an emergency and how much fuel and how many people were onboard. I replied; 'No; it sounds like a magneto; 9 gallons; and three people on board. Tower replied; 'Cleared to land Runway XR.' On short final engine died and I landed and stopped on Runway XR.Intermittent power loss is undetermined at this point.  Mechanic will checkout the engine to determine the cause.
During downwind approach pilot experiences a rough running engine and advises the Tower of the issue and the need to land opposite direction on the active runway; which is approved.  Engine quits on short final and a safe landing ensues.
