When cold starts right up runs great for about thirty minutes, sputters and then stalls, will not re start for twenty to thirty minutes. I replaced the cam, crank, idle, throttle sensors. I checked fuel rail valve plenty of pressure.

If it s repeatable then start it and let it die. Now test for fuel pressure and flow rate and check for spark when it won't restart.
Easy way to test that, As soon as it shuts down spray a bit of starting fluid in and see if it fires or tries to run. If it does you have spark but not fuel. If it doesn't try to fire you lost the ignition side.
If it's the ignition side it could be the pick-up coil in the distributor or the ignition coil.
You could also try cooling the components off using some "canned air" Simply put on a glove, flip the can upside down and give ONE part a good spray, then try starting the engine. If you can now restart the engine as soon as you spray the component you have found the problem.
