My truck died, complete electrical loss!!!

[Outfoxed]

I'm crusing on my way to work last night, drive thru a small puddle of water and poof..... I lose all power, everything just shut off. No obvious signs, no smells, no smoke nothing. The only thing that does work is my headlight switch, head/tail lights come on but nothing else, no hazards, brake, dome lights of course it does not crank either. Ground wire looks to be secure, I'll get under it today and check the power cable. But what else should I be looking at, could a fried stater cause what I've described?

Thanks Roy
