Can someone help me diagnose this problem? My 98 Accord v6 (180k miles) died out all of a sudden while I was driving. Both times after driving about 20 minutes or so and won't restart. I was able to restart it the next morning after it went dead on me after the first time. 2 days later, it went dead again as I was driving home and now couldn't get it to restart.

How do I know if it's a main relay problem? Did take it out but don't know if there's anyting wrong with it. There's some rusty crud build-ups on the circuit board. Is that normal?

Can it be the ignition coil? Because I didn't see any sparks from the wire that goes to the distributor after I tried starting it.

thanks in advance for any input.
