Voltage will drop when cranking. Normally to 10 volts or so. If cranking is stopping then I'd give the batery a full charge and see what it
reads when cranking after that.

12.2 volts indicates your battery has insufficient charge.
Charge it properly (fully charged battery should show about 12.8 volts after being off charge for about 20 minutes.
Leave over night then check the cranking voltage.
Cranking voltage under 9 volts with a battery with a decent charge normally indicates a dead cell on the battery.
Normal cranking voltage should be about 10 volts.
