hi your problem is an air leak at the carbs where they join the manifold. best way. will be to remove the carbs and change and seal the gaskets. also check the mounting nuts are tight first. may cure it.also check you have fuel in the float bown of the affected carb. its normal for the car to cut out blocking the air intake. let me know how you get on pete
