Any chance your car is dying at times also? Pin F is switched power to the ECM.
Open the clear connector. Take a small screwdriver and untang the Pin F connector and pull it out backwards. Bend the connector so the pin then makes a tight contact when inserted. Reassemble.
It might also be a problem with a less than tight crimp on the Pin F terminal. Once you have the wire out check it. Solder if needed. There is a possibility that the copper wire is broken inside the plastic coating.
I see you are installing my speedo buffer. Isn't there a replacement pin on the buffer already for pin F of C203? So the speedo buffer will replace the suspected pin correct?
I sure hope it isn't that the problem is that my pin F terminal on the speedo buffer is at fault.
btw when things disconnect electrically that should be connected we call that an open. A short is when two things connect that should not be connected.
