Is there a key light or light saying security flashing or illuminated at all when this happens you may need to reprogram your transponder in your key...putting some fuel directly in the throttle body without turning the key off after this happens and trying to start it back up would indicate if it starts again that you have a fuel issue most likely… if the computer doesn’t read the transponder in the key it’ll have similar symptoms have you run diagnostics since the condition had occurred
