most likely your ignition switch is bad. is not breaking the circuit.
Or your vehicale is running so rich (air to fuel ratio) that the catalitic converter is glowing red hot from working so hard to burn up the unburned fuel. So in theory even though you turn off the ignition which usually kills power to the coils ( the source of ignition) your car will continue to run because now the source of ignition is taking over by the red hot cats. This is most common on carbed vehicales, because fuel injected vehicales supply of gas along with ignition is killed when the ignition is switched off.

Can a blown fuse cause a car to completely shut down?
Yes, it just depends on which fuse.
What happens if the crankshaft positioning sensor fails?
If your car uses VVT(Variable Valve Timing) or adjusts its ignition timing it could cause poor fuel economy, misfires, keep the car from starting. If the car is fuel injected the timing of the injectors is tied in with that too. In short nothing could, if the car manages to keep running it could lead to a blown motor depending on how you drive.
2002 Hyundai Senata just stopped running. Went over a speed bump and car just shut off. It seems as if car is not getting any fuel. Does car have a fuel cut-off switch somewhere?
More than likely it does. Most (if not all) modern cars have a shock sensitive switch to cut off the fuel supply in case of an accident. Check the owner's manual. It is probably on the firewall behind a trim piece. It will have a reset button to turn the fuel system back on.
When car consumes fuel?
A car consumes fuel when it is running.
Can you charge a dead car battery that is disconnected from the car with another running car?
yes
