Wow, lots of variables.
You said "I could not turn the engine over." I assume you meant "with the starter" since you were able to prop it. Sounds like a simple dead battery. No charge on a generator below 1500 RPM is not unusual, so more investigation is called for. You said "fuel pressure was in the green" Did you mean "oil temperature"? If so, most cold running issues should be eliminated. Did the temperature drop below freezing the night before? If so, there could have been ice accumulation in the gascolator. What kind of Carburetor is it? If it is a Stromberg, what type of needle is installed? How fast did you advance the throttle when it died? Did you restart it and try again? Strombergs have a potential "flat spot" as the carb transitions from the idle circuit to the main jet. This can occur around 1200 - 1400 RPM and is more likely to occur in cold weather. You may have a vacuum leak or the float may be set to low (common.). If you find nothing and it happens again, try applying carb heat to see if there is an improvement. Also, try advancing the throttle more slowly, say 2-3 seconds from idle to full throttle.
