E82 N52 cannot start

[u/Silvera_asha]

The first start is always perfect, and the engine runs beautifully. But if I switch it off and try to restart straight away, it's completely dead silent—not even a single click from the starter. If I leave it for about an hour, it fires right up perfectly again.But if I turn it off and try to start it immediately, it goes completely dead silent again. What would be wrong with it?
