I’ve been searching for an answer to this problem for years. 2007 Sportsman X2 500. When riding and doing climbing or heavy work the engine would stall. It would restart but happened several times and always had a feeling that i would be stranded. Dealer found no issues. Searching online I found several mentions of the PDM (power distribution module) and ECM (electronic control module) issue on this model polaris.
I decided to take a chance and instead of having the dealer check it out, just ordered a PDM replacement. After taking the old one off, I removed the back and you can see that the OEM part never had a good seal and dirt and water got in. This looks like it caused some corrosion and perhaps some shorting when things heated up. It is mounted just in front of the radiator. Attached are the photos of what it looked like.
Thanks for the advice from the Forum. I sure I saved several hundred $ fixing it on my own.
