Narrative:

I was flying a diamond DA40 aircraft and experienced engine trouble. I believed I was going to have to make an off airport; emergency landing due to loss of power. I chose a beach and began making my approach. During this period the engine was running rough and kept sputtering and losing power. During this time I continued to adjust the mixture and throttle settings and was able to regain some power. As I made my final approach toward the beach I was able to regain power and was able to climb. I climbed to 3000 feet and returned to the airport. As I returned; the aircraft continued to run rough but I was able to maintain enough power to return.
