So there was a "updated " fuse block assembly and or recalled block for these issues sometime ago. Block assembly would be cracked and or faulty from unknown causes. Also there was the distribution board below the dash that has had numerous issues with corrosion on them and or plug issues. Sounds like you have a relay issue stopping power. Which runs through the above mentioned components. I've replaced fuse blocks and these boards before and comes back to bite you again. So. Also make sure your direction lever is also in good shape. Moisture on these machines isn't very friendly. A lot of open connections exposed to even humidity and moisture.
Even the key switches used are not very reliable.
