The easiest thing to check first is the body ground cable, is it there, is it loose, is it broken? take it off, clean the connections and reinstall it. Do the dash lights or interior lights go out when the engine dies? What do you mean that the speedometer doesn't work right? Does it bounce, Bang going into reverse intimates it has an automatic transmission, and you are driving the car when it shuts down. Des the transmission do anything strange while driving? If driving and the engine shuts down, does the car come to a stop somewhat slowly or abruptly? If abruptly, it may be the transmission going into two gears, stalling the engine.
It is most likely an electrical problem that needs more diagnosis. Is this a rust belt car, is there rust under the fuse box or where wires go from front to back in the car, or in the driver or passenger side firewall or floorboard? Does it make any difference if the headlights or parking lights are on or off? Does the car have air conditioning, if so does it make a difference if it is on or off?
It may even be the ECU quitting when hot, does the problem go away, or take longer to happen if you put an ice pack on the ECU?
Changing spark plugs "and all that" fixed this man's car.
