Anyone think this could be a bad knock sensor? If it read a misfire it would cut power immediately to prevent engine damage? The problem is if this is the case and a dealership can not recreate the problem I doubt they will fix it. If they can not get the problem sorted for you, it might be worth your while to have it replaced elsewhere to see. If it fixes the problem at that point I would send the invoice to honda corp and attempt to be reimbursed.
