Nothing worked at all until you let it cool down some? You can start by having it scanned for soft and hard codes. Check the battery connections. At the battery, at the starter, and the ground connections. Check the main relays (fuel injection, fuel pump, etc, ) when the problem occurs. See if they are energizing properly.

You say it would crank, but not start. Check the fuel pump pressure when the problem is occurring.
