Are there any codes in the computer?

Customer: replied 1 year ago.
No codes clear Kam and can complete drive cycle with no issues
Expert:  AMEDEE replied 1 year ago.

Got it! Thank you for that information. The most common cause for this condition would be a faulty camshaft position sensor, crankshaft position sensor or a valve timing problem. (incorrect valve timing)

Sorry for delay, crank sensor reads properly and vehicle will not run without this signal. Cam sensor also working properly, and is new ( old one was fine ) just pulled off timing cover and all cams are in proper timing with crank, so also not the issue
Expert:  AMEDEE replied 1 year ago.

Excellent! The next step is to check the cam and crank signals while the engine is running.

Customer: replied 1 year ago.
I have already done that, is it possible there's a miss which is throwing cam / crank sync out?
Expert:  AMEDEE replied 1 year ago.

YES, it is possible. But based on my experience, this would be due to bad tune up parts.. which you have already replaced. Unless of course you have bad new parts.
