Possible bad ECM.
Possibly low fuel pressure
lack of fuel? fuses? fuel pump gone bad?
First thought: clogged fuel filter - or - defective fuel pump.
Fuel pressure regulator.
Fuel starvation I might guess, check your fuel filter and pump.
fuel pump?
We would need to know the vehicle to answer this. To my knowledge primarily Ford used roll-over switches to shut off the fuel pump, other manufacturers use different methods, not a shut-off valve.
In the absence of a fuel system shut off as in an alarm system I would suspect a fuel pump fuse, or faulty ignition switch
my 2004 VW passat shut down cause of fuel pump problem n then of fuel pump relay problem....
A clogged fuel filter can restrict or prevent fuel flow. This would starve the engine of fuel, and cause it to shut down due to lack of fuel.
An internal combustion engine needs fuel, oxygen, and an ignition source. If any are missing, it would stop running.
If the low fuel warning light won't shut off, the fuel level sending unit has failed. The sending unit is attached to the fuel pump in the tank.
