1999 Chevrolet 1500 Engine RPM Too Low

I have a problem concerning my 1999 Chevrolet 1500 HD. My problem is when I drive sometimes it like stops running sometimes. However, I know it is not the battery and the alternator. When I start it up, I kinda runs very low on RPM’s around 500 maybe. I thought it would have been the fuel filter clogged off but I replaced it and that is not it either. Therefore, what is my problem and where should my RPM’s be running at when in park or neutral?
