How's your fuel filter look? I had similar symptoms at the track once with a clogged fuel filter. Car would run fine for 2 laps and then start missing under throttle. Fuel filter was clogged (my mistake, long story)...

As someone who tends to overcomplicate things, I try to verify the easy to check, cheap to replace stuff first...

Best of luck in your troubleshooting.
Tom
