An airplane experienced two engine power losses and was ditched about 7 nautical miles from the destination airport after fuel gauges indicated low fuel levels.

Departure and Initial Fuel Indications

Prior to departure, the left fuel quantity gauge indicated between 8 and 10 gallons, while the right gauge showed slightly more than 4 gallons. The flight departed under these fuel indications.

First Loss of Engine Power

Approximately 20 minutes after takeoff, the engine lost power. At that moment, the left fuel quantity gauge indicated 8 gallons, and the right gauge read nearly empty. During the subsequent descent, engine power was restored.

Second Loss of Engine Power and Ditching

After power was restored, a climb was initiated. However, about one minute later, the engine lost power again. The pilot initiated another descent and ultimately ditched the airplane approximately 7 nautical miles east-southeast of the destination airport. The airplane was not recovered.
