Car start sluggish when engine hot.

What is your question?

I have to turn key 3 or more times to crank car. It turns over, but will not crank--winter time, it cranks first turn of the key. In the summer, the more stops I make, the worse it is. I live in Mississippi, where sometimes its 100 degrees, I'm afraid eventually I will get stranded somewhere, where I can't get it to start--if anyone has this same problem, or solution please answer.
