Is it hard to start a GMC Sierra?

I have a 2011 GMC Sierra SLE 5.3 LC9. Recently it has been hard starting after it sits a while. The truck is stored inside at about 60 degrees. It seems to crank for about 6-7 seconds and then when it finally fires seems to stumble until it finds idle. It almost seems to be too rich.
