super duty 6.7 powerstroke 2011 starting issue

Hi everyone, if someone could help me i will appreciate i have f250 super duty 2011 with the 6.7 powerstroke engine and it says reduced engine power on the dash also the only DTC was P0335, i replace the crankshaft position sensor also the wiring and the problem consist thank you for any help...

Sebastian,

Was any work performed recently? I've seen this occur when the trigger ring isn't transferred during an engine swap.

Has wiring for the sensor been tested?

Now it starts after changing the camshaft position sensor but after 8 sec it shut off and the same message appears on the dash
