Don't think is the engine mount, trans or fuel filter.
Most probably it is electrical, could be the fuel pump electrical, intermittent contact.
Understand Nissan have some problems with the fuel pump wires in tank, check that out, pull with a little force against the wires and see if it breaks off. The wires are quite stiff so it can be in position but the wire is broken and provides intermittent contact.
