No dash lights/headlights/power windows on 2003 Pontiac Grand Am GT?

My car is the V6 GT Grand Am and sometimes it will not start. And by that it doesn't have the headlights, dash lights, or power windows but the radio works. Sometimes to fix this problem I take the fuse out and put it in and it works fine but I can't just keep doing that. Also sometimes when i get the lights to work, it doesn't want to crank over. I heard about the security relearn and that hasn't helped either. I'm running out of ideas
