Nathan Petrelli Can Fly
Nathan Petrelli never lost his powers in Heroes unless you count the eclipse when they came back naturally in season 3 episode 11 "The eclipse part 2". If you meant when did Peter Petrelli get his powers back it was in Season 3 episode 13 "dual" by injecting himself with the formula however his power was different to his original power as he could only hold on to one power at a time and he had to touch the person to absorb the power :).
