so the bike at full throttle and high revs will cut power at random, it had bad coils after the fact but have since been replaced but issue is still there. new plugs, good fuel, has air. im wondering if anyone knows if its a fuel issue or ignition issue? thanks

I had fuel issue at high RPM due to fuel filter restriction , it was just like switching the ignition off.
Perhaps when out next on a quiet road once engine is warm turn the fuel of and ride it and see if it is the the same feeling - costs nothing to try.
if the same with low fuel check fuel cap vent when it happens next open fuel cap and see if you had a vacuum ? (open cap with less than half tank of fuel to see if it helps )
You have not said if you have electrical power at the moment it cuts ?
Take it you have check all the normal stuff that cost nothing battery connections - charging - wiring to ignition switch.
