Have you checked the tightness of the battery clamps and also the earth strap too the battery terminal or body. I had the same in my fiesta where the engine would cut out for no reason and statlrt flashing saying engine system malfunction. Turns out that the ground wire on the negative terminal was loose which cut the engine out. Not a very good design tbh. Worth checking?

Unfortunately it's not possible to guess what is wrong with the car. It needs help from diagnostic kit and analysis from a garage that understands the system. I doubt if it's got anything to do with the battery and leads.

How’s the car doing now? I have a 2010 1.6 Petrol Focus Zetec I purchased this year that has been doing the same thing after numerous trips to the Ford Garages

Cluster needs repairing. It's the central part in the can bus system. The issue is dry solder joints in the Cluster unit ie the dials.
