No start symptoms:
1. Car turns over and runs for about a second, then dies after that initial "vroooom".
2. Occasionally, it will start and run for a day or two without problems.
3. This morning it cut out will doing 55 on a highway. I drifted to the shoulder, down shifted to 4th to "jump" it, down shifted to 3rd an it started again. I limped to work, turned it off. Tried to start it immediately and now I'm back at step 1.

At first I was thinking it was fuel related (maybe fuel filter). Now I'm thinking ICM.

Thanks

It never hurts to change the fuel filter, I would do it first, even if it may be the symptoms of the ICM.
Look through the troubleshooting of Hondas by TXgreasemonkey, its at top of the list after you click"Cars and Trucks", or click here:

Replace the Ignition Control Module (ICM) and coil:

You will have an external coil.

An addition to my post today:
I noticed that when the key is in position II, nothing turns on that typically turns on. That is, I can usually operate the windows and the dash lights come on. But now nothing.

Sounds like a bad ignition switch; it isn't recognizing what position the key is in, which is why nothing is powering on.

Replace the ignition switch:

For now I removed the switch and cleaned the brass contacts. Temp solution.
