P0313 after prolonged idle

I know that this subject was probably already discussed somewhere, but never found a remedy for my specific issue.
Everything is fine, until car sits and idles for a few minutes. Engine will start running rough and check engine light comes on. I would turn it off and back on - runs just fine.
Already checked DISA, cleaned idle valve and whole intake, replaced iffy hoses and rubber.
New fuel filter as well. Car has 105K miles. Can it be an old fuel pump?
