help, no start? Options

[rcrgrl]

Anybody else feel like all they ever do is ask for help fixing their car? Anyway, please help - I have no backup car this week, ice skating lessons for a 4 year old, science fair for a 4th grader and a car that is acting up!! Here's the scenario-
Yesterday afternoon, car cold, cranks over fine, no start. Try again, starts fine, idles a little low.
Drive 30 minutes, stop for 5, try to start, cranks fine, won't start. try again, does start
Drive 5 minutes, stop, - cranks, no start, tryagain, no start, 3rd try does sttart
this morning, first start of the day, starts ok, idle low, i check under the hood, there is a little dampness (gas) near fuel injector #1, nothing else. started ok though, so i go about my day, checking every stop for leaking fuel, see none.
this afternoon, repeat of yesterday. this time though, on my last stop, it took 4 trys and prayers from my kids to get it running. wouldn't bumps start either.
also, this afternoon i notice that at about 2400-3200 the engine is stumbling a little, never done this before.
i'm thinking its not gettting fuel. - or maybe too much fuel maybe the injector is going? i did just replace the pcv valve? i heard the fuel pump prime so i don't think that's it.
like i said, i have very little time today and am hoping to start looking in the right place - my thoughts are
pull & check plugs
check for spark
but as for checking the injectors, never done it?
maybe timing?

your thoughts?
