I wouldn't think it's the alternator -- otherwise, the car WOULD start -- it just wouldn't run for very long until the battery died.

You may want to check and make sure your engine's ground hasn't come loose or corroded.

Another likely candidate could be water sucked up and fouled or burnt out the MAF. or maybe there's damage to the crank position sensor?

To make sure the computer is still ok, try turning the key from off to on, and see if the guages do their usual initialization routine.

Hopefully whatever you did is nothing major.. good luck with the car.
