When flailing & failing at a repair I am ashamed to admit I am clueless so deceive myself by doing maintenance. Amazing what you find - sometimes.
So I agree ,if it is due - replace the fuel filter,check plugs, air filter,vacuum lines and electrical connections, oil &filter change.
But that is appalling advice to give in Winter !
But why does it start after you wait? What happens during the wait ,that 'fixes' the problem ?
I have found my Durametric or a SnapOn scanner sometimes identifies a problem that simple code readers do not. Maybe paying for a Durametric/PIWIS diagnostic at your local Indie is the best solution?
Let us know what the culprit is please.
