Central Air Conditioner Not Staying Cool

When I turn my central air conditioner unit on it comes on and cool air comes out, but after 30 to 45 min, it stops blowing cool air but blows room temperature air.
I called an air conditioning technician and he said I need a super boost start cap (hard start kit) for the compressor. What is that? He also said there are tight bearings in the compressor. What could cause that to happen when the pressure is good?
