Have you figured it out ? Mine does the exact same thing..it just one day decided lt was going to start this ..it will damn near put your chest in the steering wheel when the "cutt" happens. Logging shows a sudden drop in timing with the cutt off..its infuriating)
What have you tried thus far? Ignition issues can be a lot of things. How old are your plugs? Have you checked the gap? If you have an oscilloscope you can check some of the sensor outputs (CAS, crank sensor..etc).

I have chanced out the plugs ..tried denso iridium and ngk, gap@ 18k to 25k even tried the denso stock 28k gap ..it will do this and then one day it will just run normal then days or weeks later start doing it again. Ive changed the 0² sensor; tps, boost leak check, voltage and grounding check, changed out relays for fuel pump except the high low volt big relay, i reinstalled an older walboro 255 thinking it was an issue with the newer one. Ive cleaned the maf ,and map ,the problem was prior to the cleaning. The car acts like it would if you were at 20 + psi and blow a pipe the power drop is so sudden it has actually cause me to push the shifter into neutral.
