MD11 Throttle question

My last MD11 flight. When takeoff happens, advance throttle until hearing a click, but it returns to minimum; try again and again without any success. Throttle goes to CLAMP and TAKEOFF but every time goes to minimum itself. Finally I have to start the flight from the beginning (cool and dark start) to solve the problem. Any suggestion about the problem. Maybe I forgot something in the MD11 systems :( Thanks by Rob
