Sweeny11

Got thw code p0011. While driving it is fine until it gets to operatiing temperature and the car just shuts off. Then i have to wait until it cools all the way down until i can start it again. Ive read it could be my cam chain tensioner or oil pump possibly because im not getting enough oil pressure. But i checked the connections to the tensioner and im only getting 7 volts from the car to the solenoid could that be the problem?
