and Bartoli resumed on Wednesday with the Russian trailing 4-0 in the first set, which she proceeded to lose following two more breaks for rain.
However, after a see-saw second set, Sharapova levelled the match with her fifth ace before breaking again to lead 2-1 in the decider.
Bartoli, the 11th seed, broke back only for Sharapova to land a major blow in game nine and serve out for the match.
"The rain break gave me a few hours to think about things," said the four-time Grand Slam champion.
"I came out so flat yesterday. She's so tough and she was on fire. But I'm so thrilled to get back to the semi-finals."
It is the first time Sharapova has reached the last four at Flushing Meadows since she won the title six years ago.

was playing in her third Grand Slam quarter-final of the year while best friend Vinci was making her last-eight debut at a major.
The pair have won seven doubles titles in 2012, a haul which includes the French Open, but Errani's big-match experience proved decisive.
"It's always hard to play against a friend and it was strange seeing her on the other side of the net," said 10th seed Errani, who has four singles titles to her name this year.
