I'd be willing to bet it's your ignition coil, or (and this is less likely if you haven't been messing under the dizzy cap) something came loose under the distributor cap.

When the coil on my '92 EX went, it was idling normally and turned off just as if someone had turned the key to off. Then would crank normally with no results, same as your situation.

If you do a search on this forum, you'll find the resistance specs for the coil on your car (and mine). Easy to check with a volt/ohm meter.

From a price perspective, It would be best to get an oem coil (if that's the problem) from hondaautomotiveparts.com (what I should have done) as you can't really beat that price at an auto parts store, but you'll have to wait for it to be shipped.

edit: and if the timing belt broke, it would turn over faster than normal. The belt jumping several teeth so it would just shut off like that all of a sudden is very unlikely.
