Narrative:

En route VFR about 12 miles north of ZZZ airport and still in cruise I changed fuel tanks from the left tip to the full right tip. I used the fuel pump. About 30 seconds later the engine stammered and lost RPM's. I held altitude as the airspeed diminished to best glide; pulled out my emergency checklist; squawked 7700 and informed ATC that I had an emergency. A controller suggested that I turn on the fuel pump and I did so. About 30-40 seconds into the incident the engine came back to full RPM. The controller then suggested alternate air; but I declined to make any changes and proceeded toward the airport; also declining to land at another airport that was closer and a bit behind me because I preferred the flat ground ahead between me and the first airport and also saw that the engine seemed now fully functioning. I landed without incident at the airport. Fire trucks greeted me. I then had the aircraft inspected by a maintenance facility. I left it with them for over 2 hours. They ran the engine up. They told me that they noticed two inches of fuel in the left tip and the two mains were either very low or dry; and concluded that probably air was sucked in during the switch from the left tip across to the right tip. They said the aircraft seems 'fine' and suggested that I do a thorough run-up before departure. I purchased 44 gallons of fuel; did a thorough run-up and departed and flew without any incident. As there was nothing wrong with the aircraft that required any mechanical work; I did not think that a return-to-service was necessary. I have since flown the aircraft about 12 hours and everything seems fine.
