A failing ignition switch can allow the engine to start but will cut off due to excessive resistance. This is the start and would get worse when you would not be able to start.
If the lights comes on immediately after engine stalled, that should not be the problem but it it takes a while after engine stalled, that might be the ignition switch.
Such intermittent problems are not easy to detect and most probably is electrical in nature. Check the EFI and fuel pump relays.
Cutting off has different symptoms. Does it cut off immediately as if the ignition switch is turned off or it seems to sputter slightly or have fuel starvation like symptoms before stalling?
