So I was driving on the highway going about 70mph, then I noticed the motor died for a second (rpm dropped to 0 and no response with the throttle,) then it just came back to life like nothing happened. I thought this was normal before when I had a faulty main relay and the car would have a hard time starting on hot days and sometimes even dying, but i havent had any of these problems once i switched out the main relay. Could something else be wrong?

 

checked the battery and alternator output?

maybe a loose connection on the alternator (happened to me) thats not charging the battery?

 

could be the distributor on the way

 

If this is a 5th gen. I believe honda has a tsb for the ignition switch. It causes the car to die and than come right back on. Look it up if it is..

 

Sorry i should've clarified, this is a 4th gen. Thanks for the suggestions guys, I'll look into one at a time.
