1974 Spider Relay issue?

[Keveight]

I have a 74 Spider that makes a clicking sound (from relay area) and oil pressure light comes on then stalls. I can keep RPM at 2000 and it will still run most of the time but eventually stalls. Will start right back up no problem but only runs for a short time before quitting again. Electric fuel pump conversion and header but other than that stock. Any suggestions where to start?

On the 74 with electric fuel pump the oil sender unit will ground out with no oil pressure causing these symptoms. $7.50 fix but tricky. Midwest 124 Jon Logan is the man.
