Intermittent starting problems

I have a 2001 GMC Sierra 1500 with a 4.8L v8,at,ac. Every once in a while it won't start,cranks fine,act like it wants to start at first then nothing. It does have a aftermarket remote start (astrostart tx50b).I had to it towed home saturday thinking it might be the fuel pump and was going to work on it today but yesterday I sat in my backyard and accidentally bumped the button on my remote and the damn thing started,some people say fuel pump,some say fuel pressure regulator,some say something electrical,any ideas?
