I would be checking the fuel pump. One that's on it's way out will do
that: enough pressure builds up to start but not enough capacity to
even keep up with idle RPM fuel usage. A badly clogged fuel filter
can act the same way, but you should have had some warning if that was
the case (stumbling at higher RPM, etc.).
