The main relay controls the fuel mainly, Listen for the fuel pump to come on when it doesnt start or when it does. Usually cycling the key makes it easy to tell. Try cycling it on and off (with out starting a few times and listening for the fuel pump to run) it should have a distinct hum to it. If it does not come on at times then the main relay may be to blame.
I would check the Igniter control module.
It is located inside the distributor ( looks like a little box with 4 wires coming off of it. About 1-2" wide and 3 inches long. Attached to the inside of the distributor behind the rotor and shield )
Faulty Igniters tend to lead to symptoms that you explained.
It can be an expensive part, but the majority of the times ive repaired honda's with similar symptoms it was that. Hope this helps - Jay
