Hi everyone

I’m looking for some advice on an intermittent fault with my 2003 8P A3 PD140?
The problem only seems to happen under braking, car stalls, dash lights come on then the car won’t start again. There are no fault codes registered, car will crank but won’t fire almost like fuel starvation. Before the car stalls there is no erratic behaviour, everything is perfect!
Any ideas greatly appreciated.
