I had this same problem once.
Turned out to be the distributor/rotor.
The distribtor seal wore out and slowly leaked small amounts of hot oil into
the distributor while the engine would run.
Eventually, it melted/dissolved some of the softer components inside and
actually slightly warped my rotor.

Same type of thing happened. One day it was running great, then the next
min, dead as a doornail.
Replaced the dist and rotor, problems solved.

On the topic of your timing belt, as said, take off the upper timing belt
cover. If you dont see a belt wrapped around the pulley, theres a good
chance it broke. How many miles do you have on the car? have you ever had
the timing belt replaced before?
