Perhaps a really loose belt? When it gets wet it slips a lot and you have a large voltage drop from running everything instantly off your battery.
Other possibility is alternator going, if your splashing through puddle hard and fast enough, could have a alternator on the way out that when it gets wet takes a few min to then re "dry out" and work again. do you have power steering during this event? or does the AC stop working for those few seconds?
Could mount a Go-Pro in the engine bay if you had one to see the belt. My guess since their is the squeal something is going on with the belt.
