hmm, not to scare u, but it might be water has been sipped into your combustion chamber (on top of piston will have water, like sweating)....

for the first few second, its been missfiring because of the water mix...after some time, all the water gone....

happen to my n42 before and i decided for top overhaul..

adviseable to clean the MAF sensor which one of the common problem if it got dirty
