Rep Power: 0

I have a 97 honda civic ex 5 speed manual. A week ago I replace my battery and starter. My car was working fine until sunday I was working, delivering pizzas and I went into the store to get another order, came back out and tried to start my car and it did nothing. It didnt click or attempt to turn over, as if the starter went bad. I had no battery power except for my headlights and interior lights. I found out that the IG 1 (40A) fuse was blown. I replaced it today and it worked, my car was running fine all day until I went to work. I delivered a pizza to a house and when I tried starting my car up again it cranked over once and then did the same thing. No clicks, nothing but I have battery power to everything this time. I checked the fuse and it doesnt seem to be blown. What could be causing this?

Also, I replace the starter myself. Is there anything that I could have done wrong that would cause this?
