1996 suzuki intruder clutch problem?

I just bought a 96 intruder and after riding it when put into gear it would slightly lurch forward but when the clutch lever was released the clutch would not engage. I would sit there in gear as if I was in neutral. I changed the fluid and bled the line. When doing I would squeeze the lever, open the bleeder valve (fluid would shoot out 3-4 inches and then stop), only about .5 ounce of fluid would come out. After doing this the clutch seemed to work for about another 30 miles and then it did it again. Any ideas about what then problem might be?
