This may not be your symptom, but for what it's worth:
When my car would start & die immediately, it was the receiver ring for the (immobilizer) anti-theft device had failed. Essentially, what happens is that the fuel relay is activated in the start position, but not in the run position if the immobilizer does not work. So, it runs out of gas.

You won't get much help, because of the damage done and endless possibilities of the cause. If the check engine light does not come on when you loose power, then it is probably something in fuel delivery - fuel pump wiring, etc.

Because of the shock of the pothole and engine movement, you could have a loose ground wire on the driver's side, or, just a loose connector somewhere.
