Civic problem solved!

Well I replaced the main relay and ignition switch and it still died out
after a few minutes of driving. When it cooled off there was spark again and
it would start and run until it got hot again. So I put in a new igniter
from Napa. That seems to have cured the problem. At least for now! I still
don't know why the igniters in my vehicle only seem to last a year or
two................But they have not been genuine Honda parts..........

thanks for all your excellent help
