Other Fuel System problem

We were traveling north on hwy 23 in southern minnesota pulling a 5000 lb trailer in the rain and it was windy. When the road split to 4 lane I stepped on the gas to speed up from 55 to 65 and the vehicle studderd and lost all power. Many warning lights cam on and I think it said stop within . 3 miles. We pulled to the side of the road and basically coasted to a stop. It was on hybrid power. We called the nearest Toyota dealership and they suggested restarting the vehicle and see if we could make it to them. The engine did restart still with all the warnings on and we were able to drive it to the dealer being really gentle with the throttle. They pulled codes and it was intake related. They removed the air filter and it was dripping wet. The raised intake ingests water when it's raining and if it's working hard enough it pulls it through the filter into the intake and causes the vehicle to suddenly lose power which could possibly cause a accident. I am also concerned about water pulling dirt with it into the motor and causing damage. I have driven the vehicle in the rain since this happened but not pulling a trailer and really working it and so far it hasn't shut down on me yet but I've pulled the filter and it was wet. I have brought this issue to my dealer but they said they are not aware of a problem. I will attach a video of the wet filter I pulled from the air box after driving in a rain storm and a video of the warning lights that appeared. I don't think the dealership I took it too has any records of it because it was just after closing and they used a handheld scanner. They just dried our filter off and cleared the codes.
