Fiesta Flight July 2001

Fiesta with Endura 1.3 engine some times cuts out when stopping at lights in traffic etc. has happened 34 times in 6 weeks. Always restarts with no problem. Car under warranty and garage have swopped idle speed control
valve, speed sensor and I believe the engine management unit program has been updated. The car has been at garage for a week with data logger attached apparantly the car has not cut out once! Anyone any ideas on what to do next? Also where can I get information on the engine management control unit and attached sensors.
Regards Les
