I have a 2001 c5 convertible. I noticed recently that someone should pull up next to me and tell me my break lights are not working. When this happens my turn signals also are not working. I took the car straight home and after an hour I check the break lights and turn signals. They all seem to work. This has happened twice. Then I drive the car with no problem. I checked all fuses,all ok. I did research and came up with this: the hazard light switch may be going out or is bad,not sure if this has anything to do with my problem? Can anyone help with this problem?
CAC has a treasure-trove of great troubleshooters who can answer your questions. 
My first thought when I started reading your post, was in fact, the hazard switch. I'm not sure if it affects the brake lights, but makes sense. My suggestion is work that switch multi-times. Sometimes, just pushing the switch on and off multi-times can clean the contacts enough where it works again. Come to think about it, on my 2003 Pontiac Bonneville, the brake lights did the same thing and replacing the hazard switch fixed it. I think it's a good place to start.
