My guess is that your main relay could be bad. It's a common problem with Honda, Accura and so on.
Could create intermitent starting problem when temperature is extreme (hot or cold). Temperature affects one of the internal relay welded circuit contacts. The problem may occur on a random basis and could disappears for few days or weeks and reappear...
The purpose of this relay is to provide electrical power to the fuel pump.
Then when the problem occurs take off your gas cap and ear at the gas tank filler neck during an helper turn the ignition switch on (driver door closed to avoid bell sound) If you ear a kind of buz sound when the key is just turned on it's that the fuel pump is operational. If during this attempt the engine doesn't start then the problem is not your main relay. If it's the relay, it's not an expensive part and could be replaced easily (located under the dash around the steering column.
If it's not the relay I would check if i'm getting spark at the spark plugs during engine cranking. Unfortunately unless you can reproduce the problem at home it's not safe nor obvious to verify that stalled on the road.
So once again it's a guess based on the described symptom.
Some other readers could add about other components to be checked.
Hope it will help.
Let us know about development.
