check to make sure all the spark plug boots are connected properly.. i had a similar problem right after my header install my #8 spark plug boot kept slipping off the plug and of course it was the hardest to get at.. so id check there first

doesnt explain why it works better later, but it could be a fuel pump problem.

Has anything been done to it recently or before the changes happened? Start it up at night (as dark as possible) and pop the hood. Look for sparks indicating a bad connection somewhere (i.e. between coil and wire or wire and plug). This is somewhere you can start anyways.. Does it happen EVERY time you start it up? Or just first start of the morning?

Tell us some more info.
