Of course, it's difficult to properly diagnose a vehicle long distance, but I'll throw out some things you can try. I assume that you are somewhat mechanically inclined and have some basic tools to work with.
I'm gonna assume that you were driving when this occurred as opposed to a rising water situation. If that's the case, you either ingested a lot of water into the air intake and/or saturated electrical/electronic components.
In the first case (water in intake) there's two possible scenarios depending on how fast you were going and the engine was turning at the time:
- You've got a bunch of water in the intake system and it is just soaking things down and preventing proper firing.
- Or worst case, you got boatloads of water in there and have done mechanical damage to the engine. Water won't compress and if you do try to compress it something has to give, like connecting rods and pistons.
I'd start by checking the engine air filter. If it is wet and/or all wrinkly looking then you've gotten water up in there. Continue checking the ductwork leading up to the engine's throttle body. Dry all this stuff out and give it a try.
If you're still having trouble, pull the spark plugs* and check for presence of water. If there's a lot of water, disable the ignition coils (very important!) and crank the engine over with the plugs removed. This should push out any large amounts of water in the engine. Keep cranking until no more water comes out. Depending on how the intake manifold is configured, there may be water laying in there and that would require either removing the manifold or otherwise getting most of the water out. Clean and dry out the plugs, dry and re-install things and see how it goes.
If it runs OK, then you're good. You're gonna want to change the oil because there's no doubt some water in there. Also check the other vital fluids (trans, P/S, differential) for water and change as needed. You'll probably have a check engine light on due to cranking the engine with stuff disconnected. Disconnect the battery or have your mechanic clear the codes.
If it still runs crappy, you may still have water somewhere in the intake (it can hide in low spots, etc) and you can pull some plugs again to see if they're still getting wet. Repeat above if they are. If not, you've either got mechanical engine damage or some saturated electrical stuff. Electrical diagnosis might require a scan tool but usually can be fixed just by drying things. Carefully disconnecting electrical connectors and drying them may be your fix. Mechanical damage would probably require a compression test and engine teardown to see what's going on. Let's hope this is not the case.
I hope this helps in resolving you problem. Feel free to ask more questions, I'll respond the best I can. If you need to, PM me with your number and we can talk over the phone. Good luck!
*Note: a lot of Ford engine are prone to breaking spark plugs off in the engine. If this happens to you, Stop! Get the van towed to somebody with the proper tools and experience to fix this. You'll probably only make matters worse attempting to fix that on your own.

First off, Thanks to all for the input. I checked the filter and it was sopping wet and sucked in. it was bone dry from the filter to the intake. It cranked and ran.
I retraced my steps and couldn't believe I got home. My main route home was probably 6' deep, so I went another route that ended up 3' deep in the beginning, and when i turned on Krick (yep) it got deeper. I was pushing a good size wake in front so when I got to an invisible 3' dip, it only added another foot.
Bottom line is, if it had fugged my van up, I deserved it. But God protects the feebs.

It made it to my mechanic about 10 miles away. there was a noise that sounded like bearings going in my alternator. Turned out to b my belt tensioner. No problems anywhere else. My stupidity will only cost me $250 repairs plus truck rental. WAAAAAAAAAAAAAY less than I originally thought.
