Federer, the second seed, was taken to the brink by his Davis Cup team-mate before he registered a 6-3 6-7 (7-4) 7-5 victory.
"I definitely got a bit lucky out here tonight," Federer said. "Stan's an amazing player and a good friend - I'm happy to get through."
Federer will now face old foe Rafael Nadal in the quarter-final after the Spaniard eventually toppled qualifier Ernests Gulbis 4-6 6-4 7-5.
It was a good day for the leading seeds at the event, with Novak Djokovic, Tomas Berdych, Juan Martin del Potro and Jo-Wilfried Tsonga also progressing.
Top seed Djokovic made light of his late start to topple Sam Querrey 6-0 7-6 (8-6) to extend his winning run to 16 matches in 2013.
Berdych, ranked six at the tournament, was too strong for 10th-seed Richard Gasquet as he secured a 6-1 7-5 victory.
No 7 seed Martin del Potro was also a convincing winner, with 19th seed Tommy Haas blown away 6-1 6-2.
Eighth-seeded Tsonga, though, eventually saw off the challenge of the 17th-ranked Milos Raonic 4-6 7-5 6-4.
There was a mini-upset as the in-form Kevin Anderson toppled the 13th seed Gilles Simon 6-3 1-6 6-4.
