My 98 honda accord has 238,000 miles on it and I be driving down the road for about 30 minutes and all the dasboard lights come on telling me I better pull over that it is about to die on me. About 15 minutes later I can crank it back up and drive it home. I had a mechanic check it out he check fuses, distributer cap, plugs, fuel filter. He even told me change keys well I got the master key try it and it started to die on me more times than the valet key. I need help bad because one day I almost was hit trying to get off the road

This is what I would do:

. Check/replace the ignition switch:

. Check for codes.

. Replace the Ignition Control Module and coil:

. Replace the main relay, which is located left of the steering wheel.

If the problem persists, check the alternator. You may prefer to perform all tests, in Sections A and B, below:

I already had a recall on the ignition switch, coil and something else. I also check for codes but came up empty on that. I really don't know what else to do

Check the solenoid or coil. That's usually what the problem turns out to be. The part is going and until it actually goes the car will keep doing that.
