Chris,
I doubt it. Although temps below 160 may reduce h.p., you shouldn't have fallen on your face because it was cool out. I've run my 502 pretty hard while in the NC mountains and with ambient temps in the 30's and 40's. Not a reason to falter.
Better look elsewhere. As far as where, there's too many possible answers without knowing more specifics. Many components to the fuel picture outside that fuel pump and although not as many, a number of electrical considerations. With the "cough" you reference, I'd be looking at carb/fuel issues first.
A suggestion would be to start with the easiest. Looking at your plugs can be a real good barometer.
