The starter did not engage when you turned the key....
So check the battery terminals and the grounds.
No click... dash lights didn't dim.... So its possible the starter is bad, try hitting the starter body, yes I know its a bitch to even see, If it starts its the starter, either the solenoid is sticking or a internal bad connection or wire connection.
I think you must of lost all power to stall it, so check all your connections on battery and alternator.
