458 Italia intermittent no start issue

Hi this 458 Italia doesn't start sometimes and left dash screen's top bar turns light blue color and immo light goes on. i hooked up my scanner and it gives:

LF Engine - U0115 Lost Communication With Ecm/ Pcm B - Malfunction (Sig)
'' - P175B Unknown DTC
'' - P175A Unknown DTC
-------------------------------------------------------------------------
RH Engine - P0605 Unknown DTC
'' - P1663 Ion Sensing Knock Control Cyl 4 (sig)
'' - P1660 '' Cyl 1 (Sig)
'' - P1661 '' Cyl 2 (Sig)
-------------------------------------------------------------------------
Transmission System - U194D Vehcan msg mot1 invalid signal (invalid mot1 message content)
'' - U1945 Vehcan node ncma invalid signal (lost all communication with ncm)



I immediately though about the male & female connectors(common fault). But this symptom only occurs when i START the car & turn off and immediately start again. So i checked the BCM and it's VIN says Not available. I'm thinking of Immo off for this car if it's not the wiring issue. All i pray is for that there is someone who has experienced this before and can save me time!

 

Battery is new and is OK.
