CAS issues

[Adrian's Vr]

So few months ago my car would start to cut out and after 2 minutes of on and off it finally cut out but starts up again, only happens in the morning when its cold, then one day it completely cut off and I changed my DFI module and coils from a old motor, now its 6 months later and its doing the same thing, but this time it throws a battery light and all my lights dim completely, DFI or CAS? Even alternator

Check your alternator.
