Problem of 2000 Accord. HELP!

I just got off highway. I noticed the engine was off and got back without ignition for 1 second. Meanwhile, all things on the front panel were off and back to normal. Anyone thoughts are appreciated.

I'm sorry, I'm not exactly sure what you are describing. Do you mean while you were driving, the engine shut off momentarily and then came back on? If so, you may want to check your battery cables and make sure they are tightly secured. I once had a loose battery cable that caused the same thing.
But if that doesn't fix it, or if I misunderstood, please try and be a bit more descriptive of the problem.

Thank you very much! Now I also suspect that the problem is caused by the electrical system. Because when I start the car and turn on the front light, the same problem (all things on front panel went off) appeared. I have checked the battery and found that there are some thing like oil on the connector between the cable and the battery. I cleaned the connector and hope this can solve this problem. Thanks again for your help :lol:

I believe that "oil" you found was the anti-corrosion grease. As for the lights going "off", do you mean turning on and flashing? This is normal at start-up, but if they come on and stay on, then you should get your OBD-II codes pulled of your CEL (Check Engine Light) comes on and stays on.

If this isn't the case, then I am probably misenterprating your post.

Maybe I didn't express myself clearly. I mean sometimes all of things on the front panel including meters and lights would go off and come back 1 sec later. So I believe there is a problem in the electrical system, and I am trying to figure it out. Anyway, thanks a lot for your help!

......... you may want to check your battery cables and make sure they are tightly secured. I once had a loose battery cable that caused the same thing......

if your car is started and you disconnect the battery cable/s it should run off the alternators power. if it does not do so than your alt is either bad or is going bad (not putting out the full voltage).
