You need to consult Nissan Service Shop at Industrial Area. Similar thing happened to me 2 years back while I was in Oman. The problem they told me was with fuel forwarding pump (there was a crack on the fuel forwarding pump, might have caused by hitting the car bottom while crossing road humps). But they eventually replaced even the CVT, as they were not 100% sure it was due to fuel pump(It was under warranty period, so I didn't bother)
