For that 1 min, you car alternator died and again got life back. Keep a close eye, if it happen again switch off all lights ( as your battery stops getting charged) including headlights and just drive home or to near mechanic and get new alternator. It cud take 2 years also and 2 days also to fail. No one knows.

Remove the battery and re fix after few minutes. if you can shift to neutral its great. Drive the car and go to the mechanic. If not then call a recovery guys and ask them to be gentle. Check engine light needs a technician who have OBD II computer to read the fault code and clear it (if its minor)

No can guarantee that, but usual suspect is lifter while engine start clicking too much. If not the valve or tappets. You can even diagnose these mechanical issue in computer that can tell you 100% correctly. You got to take the shot, better take 2 or 3 more mechanic opinion after they hear the noise they can advise better.
