RPM dropping and shuts down after starting

1978 930 start normally and idles at 1000 RPM then a few minutes later RPM drops and the car shut down but both fuel pump still running. If when RPM drops down I accelerate to keep it up, it at first chock then it hesitate and RPM goes up. I cleaned the WUR, auxilary air valve, fuel filter. It takes longer for the RPM to drop but still the same problem. I need some help. The problem is probably staring right at me and I do not see it. What are your thoughts. Thank you.
