Do you mean all electrical power or the engine will loose power and stall?
Will the engine crank over after it shuts down?
We need to see if it is a charging system problem or a separate electrical concern. If you have a meter, start the engine and see what the voltage is at the battery with the engine running. It should be 13.5 volts. Then, when the vehicle stalls, check the voltage at the battery when it will not start and also check and see if the headlights and/or parking lights come on.
Please let me know the results.
I completely understand. But there are no known causes for this concern. Although, you may want to inspect the ignition switch on the steering column. Also, check the battery cables and the charging system. If the alternator is overcharging, it can cause the same issue.
Disconnect the electrical connector from the ignition switch and check it for burnt pins or brown spots in the connector and the switch.
