Sorry to hear about all your issues. Based on your previous posts it sounds like there have been a number of corrective measures attempted in the form of parts, computer scans, battery replacement etc.
The fact nothing you have done seems to have corrected the issue makes it sound more likely to me you may have a bad electronic control module. The ECM is the brain of your Spyder. Although not a common fail item it’s not unheard of for them to go bad either which can cause issues with running properly, transmission shifting issues, throwing codes, etc. There is no way to test this other than replacement unfortunately and really is a last resort if every other conceivable thing that could cause this has been looked into (sensors, oil levels, BUDS scans). I really think the ECM in your case should be considered suspect if your dealer hasn’t. I do hope I’m wrong because it won’t be cheap however you may need to begin preparing yourself. Let us know how you make out and good luck!
