Had a similar problem with a cb650. It was the gas cap not venting correctly. Also, improper set (or restricted) idle air needle valve can sometimes drive you crazy. Anyway, sure sounds like a fuel problem to me. Could also drain the carb bowls to make sure residual additives like fuel stabilizer has not pooled in the bottom. I once had this and I couldn't start it at all. I had used fuel stabilizer coupled with a Seafoam treatment...they did not mix well!
