Might have better luck in a different section, but is it EFI or carb? Any mods like stage 1 and does it have a tuner (if EFI)? Happen when its hot or right off the bat?

I've seen crank position sensors cause similar conditions. They sense the notches on the flywheel and will send a trigger signal to the ignition system for proper plug firing. Just something to be mindful of.
