fuel cut happens when you suck in the dense air too much for certain period of the time. So, your MAF sensor reading will be very high. When your ECU sees this spike, it will cut off the fuel. It can also happen when your engine knocks like crazy or fuel pump fails...etc.

Your motor probably misfired. Replace all your plugs with NGK BPR8ES plugs. Its around that time to swap plugs anyways. When your car misfires, you'll feel a buck and lose power instantly. You basically run on 3 cylinders if one cylinder misfired. Sometimes it may lose power, buck, and then suddenly come back to life as the cylinder sparks up again. Misfiring is generally a problem with the spark plugs and wires. Definitely check your plugs and wires. A misfire feels like youre hitting fuel cut.
Fut cut, funny, but true, but I have only experienced that one when tuned very aggresively, or when flooring it at high RPM....... took a while to get of the flash feeling 
That is knockinh however, flashing CEL......do you have any light come on at all? Doesn't sound like it, and a misfire would definately give the po300 code?

that doesn't sound like fuel cut to me. WHen you hit fuel cut you will know, its like hitting a brick wall.
what your describing seems more like just breaking up from running too rich up top. I had the same problem with simular mods, get an SAFC or a tune and you'll be all set.
it prolly wouldn't hurt to check your plugs though if they have 30k miles on them.
