The car will drive fine for an hour and then not run anymore. It will start to act like it is low on gas and start lurching like its trying to get fuel or air. After it dies it will not start up for about an hour and then it will do the same thing all over again after driving for 30-45 mins.

Work done to the car so far is starter replaced, CAM sensor replaced, ECM replaced, but the problem persists.

Has been difficult to trouble shoot as the car will run but as soon as it dies you can not get the car started again till it appears to cool off.

Hi dauntlless,

Looks like something is not functioning properly when it heats up.
There are many possibilities with poor connections of wires.
If it is electrical, you need to have a look at the ignition coil.
If it is fuel, the pump or its realy.
When the engine stalls, check and test for the above.
