Engine cutting out when slow and clutch depressed

Hi,
I have a 95 Ford Escort 16V 'Atlanta'.. and am having an issue where it stalls even when the clutch is fully depressed. (edit- just looked around, and it's possibly not stalling.. but rather cutting out.. there's no jerkiness or noise like when it stalls..)
In the last month, it has happened twice..
I'll try to describe exactly how it happened, although I may be misremembering slightly..
What I can remember is: Approaching a tight corner... I was approaching slowly in 2nd.. and then...
