I have an 04 chop and it ran fine with no issue up until about 3 months ago, all the same shit you're describing, kinda makes you feel like you're going nuts with all this unexplained weird shit going on, especially when it just dies at 70 or so, that's always a treat! Eventually it just died one day on the road and wouldn't restart. Ditched the EHC, got a hold of Jake to get everything I needed and put the 6K HID light in while I was at it. After I was done the bike started the first time, done deal, no issues what so ever since the install and you can do this yourslef :2thumbs:
