Hello and welcome to the forum.
If the engine isn't turning over when the fault occurs,it's not the immobiliser causing the problem.More commonly it's either a poor battery connection,a corroded earth connection between the battery and the engine/body,a faulty starter motor,or a corroded connection between the fire/exciter wire and the starter motor (the smaller wire running to the starter).
I'd rather push my Alfa than drive a BMW....
