Oooooooo! I think I finally fixed it! Found a VERY loose connector between the frame and the motor all the way at the front. Someone recommended checking the dreaded "Green Connector" and, while it was fine, when I was trying to get it loose, I nudged the black connector next to it and it popped wide open. Totally explains the symptoms and the blown fuse. While I was there I de-snorkeled it out of spite lol. Took it for a quick ride, and it felt pretty sprightly. The TRE probably had a lot to do with that, it did feel really peppy down low. So far, I'm a fan, and *fingers crossed* actually fixed it properly.
Tomorrow the wife and I are going to Cycle Gear to get a new jacket and a pair of gloves for her. We'll probably have her drive and I'll take the bike in the chance that it's still having an issue, so we're not both stranded lol
