2006 Honda Odyssey engine shut after ten seconds

My car engine shut down on the highway while driving and won't start again, I towed to a mechanic workshop where it was discovered that exhaust catalyst had broken and blocked engine air flow. It was dislodged, starting it again became another problem when it eventually started it vibrated and stopped after few minutes. Anyone with similar problem and how it was solved please help me out. We've changed sensors but it persists. When it does starts it lasted for only ten seconds and shut down.
