Bad Cam Position Sensor?

I have an 03 6.0 with 60k on it. The truck runs great, absolutely no problems... until I turn it off. When turned off it will not restart and throws a cam position sensor code. I have to wait until the truck cools down and then it fires right up again. Replacing the cps in the morning. Does this sound about right or could it be something else causing the problem?

Without some live sensor data it is hard to say, could be a number of things. FICM voltages; ICP pressue too low etc.

Replacing the cps did nothing. We did a pressure test on the oil system. When cold the high pressure oil pump puts out in the mid 600s range. When having the no start issue it only puts out in the mid 300s. The pump was replaced two years ago so I don't think it gone bad but we can't find a leak anywhere. Any suggestions?

Excessive cranking with no start can throw cam and crank sensor codes. Only 300 psi during cranking sounds like a HPO leak. Bad IPR, blown injector o-ring, standpipe o-ring, or blown flex line which connects the stand pipe to the rail or even one of the snap to connects fitting between stand pipe and flex line, flex line and rail. Wouldnt rule out a failing HPOP either
