Driving my car 20mile today for m.o.t and at the end of my journey car cuts out and says oil pressure stop engine. Car wouldn't start but would crank. Wen I leave it to cool down it starts again until hot when it cuts out again wen up to temp. Epc light also comes on.  Diagnostic shows engine speed sensor and broken circuit, But nothing for oil pressure. I have a inlet manifold gasket that needs changed as its leaking oil. Oil carch tank would be handy to invest in.. Oil levels all ok tho.. Engine code agz. Looked through loom and found no broken wires, so what's the problem, oil pressure or engine speed?? Please help, il be very thankfull

the engine speed sensor/crank sensor is most likely the only issue. the erratic rpm signal from the crank sensor will be sending false triggers for the oil pressure warning. Could be a wiring fault but sensor failure is pretty common.
