Wiring problems of the 2006 Dodge Durango

I have a 2006 Dodge Durango, bought it used about 4 years ago. About a year and half ago, approximately March of 2013, the vehicle started to stall while driving. It happened at all speeds and after it happening multiple times we figured out that it happened when it was wet/raining out. This is extremely scary and dangerous when going 70mph on the highway. . . To have your vehicle jerk numerous times and then completely shutoff (aka no power at all!). We have spent a few thousand dollars since spring of 2013 trying to fix the issue. We worked closely with our dealer to figure out the exact problem. . . Figured out it was electrical (possibly when the windshield wiper are used. . . )but that was about as far as we got. Some of the things they found and/or fixed or replaced are as follows: wiring that was frayed, re-ground numerous wires, replaced a handful of sensors, resealed connections between electrical components and main module (as well as resealed the boxes themselves since water was found in them), replaced the electrical module ($2k), and replaced entire electrical box(which included having to re-wire). . . Found a used one since brand new would have been $1200! . I have recently seen that there was a petition to the government to investigate (and hopefully recall) vehicles that have situations similar to what I have described above but they reference vehicles manufactured 2007 and forward but our 2006 is having the same issues!! since it has been to the dealer last (less than a month ago) we have not had the problem but there was a stretch over the winter where it didn't happen at all either so I am not convinced it is fixed. . . It seems the dealer mechanic is about out of ideas and so are we. . .
