How did this happen?

96 Honda EX 120K Manual Trans

I was driving 2 weeks ago and my car jerked and just died. I had it towed to a repair shop and they replaced the distributor and I also had a full tune up to replace the cables and cap. Everything seemed to be okay but when I got off of work today, my car won't start. I had to have it jumped to start it and I figured I probably just left the light on or something but when I got home, I tried turning off the ignition and turning it back on but it won't start again. I don't know if this had anything to do with the part that they put 2 weeks ago (still under warranty) or if this is just a new problem (i.E starter or alternator). I'm so confused right now. I would really appreciate all the help. Thanks a lot!
