A/C Intermittently Not Working on 1999 Acura Integra

A/C is working most of the time, but when I go out on Sat.'s about 1-2p, in the hottest part of the day, the A/C will quit being cold about 10 min. out & it doesn't come back on. I recently had the A/C fan (& motor) replaced. I have taken it to the dealer for the recent problem, but they could not duplicate the issue. Any suggestions?
