Car Died AGAIN please help!!

on my way to work yesterday my car just died again while I was driving. Its not getting spark in 3 cylinders. I changed the ignition coil only 2 months ago. What can it be this time?? Pretty sure its the distributor cuz no spark and its gettin fuel but what part of the dizzy??? Any advice would help, thanks!!

cap and rotor?

well after 80 bux for a tow truck it was a measly 6 bux to fix the problem which was the rotor!!! thanks for the advice though, those were my first possibilties that it could have been.
