There are many things that could be your problem and for someone just to guess would be like playing black jack in Vegas. See if you can find someone with a scan tool to see what is happening with your sensors and fuel management system. Do you know any Vette people in your town who could do a scan for you? Your posting in the "tech" section indicates you did not have any stored ECM codes.

Newb to the forum but 35 years of cussing these things 
If it was a "sudden" event then I would suspect a vacuum leak...if it was a gradual thing....(gradually got worse to the point you describe) it could be a IAC Valve/Dirty Throttle Body etc.....I am curious how it ran after it achieved open loop though.....did it smooth out as it warmed up?
