Not neccessarily saying it's a fuel pump failure, but a pressure check, especially a running check when the problem occurs can eliminate it from the picture.
Cracked plug, it should run like poo at all times.
There are a few ignition components that can cause these symptoms, BUT, anytime I hear "sputters" I tend to lean toward eliminating the fuel system.
