Keep in mind that the +12 from the EFI relay passes through an additional 2 splice points and 1 connector before it gets to the COR. If the +12 to the COR is becoming intermittent, then replacing the EFI relay would have no effect.
intermittent problems like this are difficult at best to diagnose. I would suggest removing the relay box in the left kick and looking closely at relay contacts and associated wiring for the COR.
However, we're still shooting in the dark until this can be verified as a fuel delivery issue.
