I had the same thing happen to me prior to my first marathon. Stay on top of your nutrition prior to and during the race, and don't be surprised if your energy goes sooner than you expect. I believe in my case it caused "the wall" to hit me much sooner, so don't be too hard on yourself if you can't perform the way you know you have prepared to.
