This morning when slowing and dipping the clutch to change down to second gear to turn into a side road my engine cut out and hence the power steering didn't work and luckily i managed to re start it in time to carry on driving.

It also does this when approaching lights and dipping the clutch before coming to a halt the engine will die. This is happening more often, once or twice a week maybe. The battery is a Bosch item, relatively new and my voltmeter is showing high 13's/low 14's most of the time and it doesn't struggle to start in a morning.

Can anyone diagnose the problem?

Battery/alternator perhaps?

Cheers.
