Could it be Tran? on 2006 Nissan Murano

My car broke down at a red light, it starts and when I hit the gas it doesn't move. Eventually the engine shuts down

It's hard to tell. CVT transmissions are prone to fail, but usually there are problems with them before they break down completely.
You really need to tow it to a good repair shop and ask them for diagnostics.
Based on the results they can tell you what's the problem is and the cost of the repair.
