Power loss when wet.

[MillwrightJay]

I have a 2001 1500 5.2. Just bought it a few weeks ago and have no problems until yesterday, I had been driving for 4hrs ( all hwy) and had no problems with it until just before i made it home I hit a couple of slushy spots. almost immediately after going through one of these spots my truck started to lose power, was bogging down and I couldn't get it up past 30km/hr. I pulled over and when I put the truck in neutral I had no problems getting as much rpm as I wanted ( no bogging ). I was able to get the truck the last 20min of my trip by repeatedly stepping on and off the gas bringing the truck up to speed. later in the day after being parked for a few hours I took it for a ride and had no problems, then today still no problems brought the truck to the self wash to get all the salt from the trip off it and again same problem as yesterday.

Anyone have any Ideas? wet plug wires? maybe a sensor getting wet causing this. Looking for a place to start. thanks in advance.
