When i do a long run (4 miles) or tempo run, I will get a sharp pain suddenly causing me to slow down to a walk. I will then proceed to ice when I get back home. Any ideas what it might be.

I agree with others you should ask a medical professional if it continues to cause pain.
My advice is not professional, but do you think this might be a calf cramp? This can be caused by lack of vitamins, including phosphorus, magnesium, calcium, sodium and potassium. However, it seems that potassium can be the most important vitamin to prevent cramping. I used to get sharp pains in my calves when deficient in potassium. Foods high in potassium include avocados, bananas, dried apricots, mushrooms, spinach, and salmon, among many others.
