I have got a 1995 prelude 2.2 vtec with 4ws

I changed the spark plugs on my car a few days ago and the car was running ok afterwards.

I then decided to change the ignition leads, I placed the leads on one by one in the order I took them off the car, I then started the car and it ran ok.
The next day I started the car and it run ok for about 15 seconds then started to chugger and spit, then it stopped - I looked at the leads to find one of them had come off from the distributor cap. after replacing it back on in the same place the car would not restart. and I am unsure what to do next.... ....can you please help me!
