2007 dodge ram 1500 truck code P0522... seems common?engine shuts down disconnect battery restarts.

engine oil pressure to low posible bad oil pressure sending unit o engine internal proble o no oil on engine or electrical problem

cranks ok but wont start and battery is charged to 12.6v dc rested?>
and wont jumper cable start>>>>>>??????????????????????
which engine>?
start with gas cap off?
2 problems, if wont start cap off.
tank vent system issues,
522 is the one.
P0522 Dodge - Engine Oil Pressure Sensor/Switch Circuit Low Voltage

the PCM sees no oil pressure and refused to start.
sounds like a winner there. huh.?

ok, so check oil pressure.
if good , then the switch is bad, or wires to it bad, fell off.
Sig: I must ask questions first, I'm blind, and my tools can't reach, dig?

You could've gotten dirt or grease inside the cam sensor connection. They are real fussy.

Evap system leak, oil pressure switch and o2 sensor

install mechanical guage and check oil pressure could be a bad oil pump or engine failure

P0232....Fuel Pump Secondary Circuit High

P0230....Fuel Pump Primary Circuit

P0215....Engine Shutoff Solenoid

P0122....Throttle/Pedal Position Sensor/Switch A Circuit Low Input

P0522....Engine Oil Pressure Sensor/Switch Low Voltage

p0440-Evaporator Emissions Control Malfunction. P0522- Engine Oil pressure low. Replace the Gas cap and double check your engine oil level to make sure your not low. Reset the computer and see if the codes return. If your oil level is good when you check it you may have a problem with your oil pump.

I'm assuming you checked the obvious...and no blue smoke.

Was that from an OBD error code reading?
P0522-ENGINE OIL PRESSURE TOO LOW 3.7L, 4.7L

Could be you ran engine low on oil or went up (down?) incline to trip the low pressure sensor.

and or Viscosity of oil is too thin, in either case get oil changed pronto, reset OBD and check levels often. hopefully was a costly mistake ...yet.

Your sensor could be damaged. Keep an eye on engine temp and coolant. pressure test cooling system if possible.

Good luck

First thing I'd check would be battery cables, at both ends for clean, good & tight. Does it ever do it while driving at highway speeds or just at slow speeds? Wet out, dry out?

Code 12 doesn't correlate, but Code 1282 may provide some insight. Code 1282 is "The fuel pump relay circuit seems to be having a problem", which would explain the disconnect/reconnect trick that sporadically works. Have the relay circuit looked at.
