Hmmm... If it stalled and won't turn over, that sounds like a seized engine. Do you get ANY sound when you turn the key to start or do the lights dim?
This is a very basic trouble shoot -
If the lights dim when you turn the key to start and you hear nothing, then the starter is getting power, but can't turn. If that's the case, the engine is stuck where it's at.
If you get absolutely no sound or light dimming when you turn the key, then the starter could be out, but that doesn't explain the stall out of the engine.
Check your oil - make sure you have oil on the stick after wiping and reinserting.
Yes, these are really basic basic things, but may take us to step 2.
