Hi in response to this what can seem a tricky question personal experience tells me you have a cracked rubber lip on your air intake manifold when the rubber warms up the crack expands allowing too much air in so your engine will stall. have a look and see for yourself or inform you mechanic to replace the in take air manifold and keep me informed ok?
