The 29-year-old from Dusseldorf began the round with a six-stroke lead after a historic 36-hole start on 10-under 130, the lowest in US Open history.
But with tougher pin placements on Saturday, Kaymer made three bogeys in the first six holes against an eagle at the par-5 fifth.
After a bogey at six, Kaymer ended the roller-coaster ride and parred six holes in a row until a bogey at 13 and a five-foot par putt miss for bogey at 15 left him on seven-under.
Kaymer closed by sinking an eight-foot birdie putt to stretch his margin to five strokes in front of Americans Rickie Fowler and Erik Compton, both on 207 after three-under 67s, the only sub-par rounds of the day.
Sweden's Henrik Stenson and American Dustin Johnson shared fourth on 208 after each fired a 70, with American Brandt Snedeker the only other player under par on 209 after a 72 Saturday.
