Cutting out/ stalling when engine warms up

[k.channon1991]

Having an issue with our micra. Runs totally fine for about 15/20 mins then will cut out as if it’s running out of fuel. All warning lights come onto the dash and wont restart. After half an hour cooling down will run but the same thing happens again. Garage can’t seem to find any faults. I read somewhere about it being a potential issue with the throttle sensor but can’t seem to find any more info. Any help really appreciated. It’s a great car with no other issues will be a shame to scrap it. Thanks in advance
