2000 blazer long starts
 

I'm new to this forum and I figured I'd give it a shot and ask you folks what you think my problem might be. I have a 2000 4dr 4x4 blazer 4.3l v6. The problem I'm having is on cold starts it has a really long start but if I shut it off and start it back up it starts right back up. Here's the thing that gets me first time starting it in the morning though it starts right up but once I shut it off and let it sit a couple minutes and go to restart it it has a long start. Any clues on what this might be. Also it has a remote starter incase that helps
