7.3 cutting out

a few weeks ago, i noticed this problem as i was driving home from work. the motor cut out(like made a small jerk) and returned to normal..i went farther down the road and it did it again and then once more about 5 minutes later..the check engine light does not come on until it does it 3 times and once it does come on, the next time it cuts out, it actually stalls..also when it cuts out, the RPM guage does not go to zero and ive replaced my CPS twice. But heres the kicker...IT ONLY HAPPENS WHEN IT RAINS OR IS WET OUT LOL. I just dont understand it...and i know it isnt the tires slipping i can tell its the engine
i think its something electrical that doesnt like to be wet?
i just dont get it
Anyone know?

Thanks

Sure sounds like a CPS but you have replaced that. Did you use dieelectric grease to seal it? Maybe the fuel pump is on i's way out. Check your UVC harnesses with a wiggle test. Better yet, check for any codes.

344 is one of the CPS codes. what brand CPS did you use, I have seen some of the new aftermarket (CarQuest) brands cause that right out of the bag.
