I ran out of gas over a week ago, since then my car hesitates when I start it. Today I went to drive and giving it gas it won't go. I had it floored and only got up to 11 mph.. Please help?

In tank fuel pumps are cooled and lubricated by the fuel in the tank. When you run a car out of gas or very low, it pumps a lot of air through the pump which overheats it and causes some severe wear and many times, failure when they cool off.
You will need to use a fuel pressure gauge to verify this
