Mixture solenoid Quadrajet carburetor? I might start in that neighborhood if it has that carb. Quite cantankerous if not in freshly rebuilt and operating mode. Can cause more than mild symptoms. All your electrical connections and engine/body grounds in good shape? Trying to rule out ignition breakdown so you can focus on fuel delivery, which is my suspicion in this case. Let me know what you find. Thanks, TT
