Narrative:

We executed a go-around while approaching to land after getting an 'airspeed low' warning and stick shaker. Both the first officer (pilot not flying) and I noticed a brief illumination of the le flap in transit light. We consulted the QRH and performed the procedures for a flaps 15 landing. Opc data indicated a safe landing; and we asked for clearance to land. While configured at flaps 15 and landing gear down on speed; we received the same warning and stick shaker at 500 ft AGL and performed another go-around. I flew the aircraft and the pilot not flying contacted maintenance for additional guidance. I advised ATC we were low fuel and needed a close in vector to perform the QRH procedure. ATC was congested and I declared a fuel emergency to get expedited handling back to the airport. I called the flight attendants and told them to prepare the cabin; but we expected not to evacuate the cabin. We computed opc data for a flaps 15 landing and flew an uneventful approach and landing. Both pilot flying and pilot not flying were task saturated with ATC and dispatch while performing QRH procedures. Had our fuel state been not as critical; I would have briefed the flight attendants more thoroughly.
