How deep was this "puddle"? If you went in to a deep amount of water say deep enough for the water to come up to the drivers door, you introduced water in to the engine comaprtment. I would start by checking the air filter to see if it is wet. If it is replace it. I would also pull a spark plug wire and see if there is water in there. If there is I would dry these out with paper towel and wipe the top of the spark plugs. Do not use any kind of spray, you could cause an explosion or fire.

A car will stall when driven through standing water if the ignition system is not watertight. Worn spark plug wires and coil wire, improperly seated spark plug wires, or loose distributor cap are all possibilities.
There is a spray called CRC or some agent that promotes a water drying action can be used to dry out a wet distributor cap and wires. Drying off the electrical components will remove the moisture that is grounding the electrical energy that should normally go directly to the spark plugs.
If car will not restart after stalling from the water splashing as described in the question - and the poor condition of the electrical system is ruled out, some water may have passed through the air intake into the engine and perhaps into the cylinder. If this happens have the car towed to a repair shop where they can remove the water before any further damage results. This condition is not easy to occur but a real deep puddle can set the stage for water to be sucked into the air intake and pass through the filter into the intake and through the valves into the cylinders. This is why you see a Hummer with a snorkel - for wading through deep water.
