Had to get it towed back to the garage who can't figure it out and say it's not their fault but an electric fault.
Anyone any ideas please?
Have you tried another battery and had the alternator checked. I do not believe in coincidences like this.
Sounds like the alternator failed and you were running on just the battery or vies versa.
