Opel Corsa lite cutting out while driving

This old could be a thermal problem in the ignition system, possible an ignition module or trigger sensor. This is assuming the normal things like the engine tune and plugs and wires are in good condition.

Thank you for your replies. The car cuts out while driving up hill, on a straight, down hill, once while I was turning, only 2 keys on the ring so not weighed down. (Only 32 thousand clicks on the clock). She also starts immediately after she has cut out. Once I have noticed she wants to die when stopping at a traffic light but eventually she stabilises idling.

Wanting to die at a stop is usually a sign of a dirty or nonfunctional ISC. Check for dirty throttle plates. Still sounds like an ignition componet.

sounds like a timing issue make sure everything is firint correctly
