check the main relay common issue with honda's. they get warm and end up getting a break in the connection then when they sit they can cool and the connection may connect again. but could be wrong

Never heard of main fuel relay issue in this generation civic. I have found a few with Mass Airflow sensor issues. Since your throwing parts at it, try a mass airflow sensor. Good luck.
