Help Troubleshooting?

I am not sure if this is the right place for this post, but I own a 2004 Ford Mustang V6 Convertible, and I need help either troubleshooting this problem I am having, or for someone to tell me I don't have a problem at all.

Today I was driving and hit some heavy traffic as a result of a lane closure. I was stuck in 90 degree weather for 90 minutes traveling only a few feet per second when, all of a sudden about 40 minutes into the drive, my car's RPM dropped, and sounded like it was going to stall. I hit the gas to boost the RPM's, and about 10 minutes later it happened again. I once again tapped the gas, but the third time it happened I just threw my hands up and decided to see if it would stall.

It did not stall, however it got to the point of almost cutting off before kicking up the RPM's. My step dad, who is mechanically inclined, seems to believe that the combination of heat and the long drive time and start and stop traffic cause strain to be placed on the compressor and that it had to draw upon the motor to sustain operation, thus lowering my RPM.

What I need to know is if there is anyone here who has had a similar problem during hot weather and extended slow drive times, or if this is something I need to have checked out. The car has 102,000 miles on it, and I have owned it for about 8 months. Any information or ideas as to the cause of this would be great.
