Ok, The code on this one says it all. The cam sensor losing signal will make it hard to start because without cam and crank signal, the computer will shut down the spark and fuel.
I would start with a new cam sensor from the dealer to resolve the issue. The aftermarket sensors aren't up to date and can sometimes cause issues.
