Starting Issues?!?

[Kalons 07 LT3]

So when my Tahoe is cold, and i try to start it, it will crank and crank for several seconds before it starts. However i can just let it turn over for a second, turn the key to off, and then crank on it and it starts right up. Im confused. Anyone else have these issues?
