I would need to know what the actual code was to comment, but the problem could be what the sensor "watches" on the camshaft, or the wiring harness going back to the computer.

Whom ever replaced the sensor, must have
done so, based on the code & not on testing
to find out why the code was set.
Codes do not tell you what is wrong or to replace
any parts.
My advice would be to find a shop that is the best around
at diagnosing vehicles,I wish I could give you a guide &
questions to ask in your search but I can't
You will have to ask other people where they go to
& what type issues they had & the shops can resolve.
On a vehicle 10 years old & for those who never change their
oil on a new vehicle & that includes most people,you could have
mechanical problems
A sensor reports an out of range condition,so if you have no
wiring issues or other sensors pulling that one down,mechanical
issues are a good place to look
The way to do that is using an oscilloscope & the proper
software,& not every shop has that-- shall we say equipment,
knowledge & skill level.
Use your codes & Google them & your vehicle & look for
known issues with whatever motor you have.

2011 Malibu. Got code readings of p0010/11 and the O2 code. Replaced the O2 & camshaft sensors and the cam solenoids. Still starts fine but dies as if not getting gas.

code p 0010 refers to the camshaft position actuator(CMP) intake /left/ front bank 1--circuit malfunction====causes --wiring--CMP actuator--ECM
code p 0011 refers tocan m shaft actuator (CMP) intake /front/ left-bank 1--timing over advaced/ system malfunction ====causes ---valve timing--engine mechanical fault--CMP actuator--Wiring
you say you replaced the sensor but that was not the indicated fault
It is the actuator , the part that advances / retards the valve timing for that cam shaft according to engine rpm

cam sensor it also linked to the crank sensor usually if the cam sensor fails around the same time the crank can become un synced with the replacement. or the new sensor is not the correct one, ie sensor from a 1998 model will sometimes work on a 2005 model if it has the same ecu fitted in the 2005 not the hole ecu but the chip. on the cam sensor there is say in some cases 3 poles positive feed negative and then signal. on all the poles there is a resistance between poles that the ecu reeds. it reads the voltage being used and the signal its receiving if one of these is wrong but it detects one of the readings being right it will think the other sensor is wrong. and thats a mis match. the resistance changes over time.

Car will start but dies after about 10 minutes. Will restart after about 5 minutes but dies again after running a minute. Replaced fuel pump, fuel filter, attempted to clear codes by disconnecting battery,...

Check and see if you have spark when it won't start. If it don't check the ignition module, Coil Packs,Crank and Cam Sensors. See if that gets in the right direction and let me know if not get back we will see if there is some more things we can look at. Ok thanks Bear001
