Random Stalling?

[k_teven]

I think this is my first question to the forum so I will try to do it right and not droll on..

I have a 2010 RT/SE5. Odo shows around 25K miles now, had about 16K on it when I purchased it. I have not replaced anything other than oil and filters since owning it (about 3 years). The fuel cap was a recall item that was replaced.

Yesterday when riding home from work, it began losing power quickly and even though the throttle responded, it was still coasting down to a stop. Got it down to 3rd and the engine quit all together. Pulled off, applied brake and it started back up, nothing unusual in the display. Downshifted to 1st and began home again. About 5 minutes later, same thing happened. It seemed like getting it into 3rd during downshifting actually coincided with the engine shutting off. Restarted, downshifted, took off for home. Got the rest of the way home with no other issues. That was about 20 minute ride at that point.

I checked it at home for codes (running at idle, holding mode and selector simultaneously while depressing turn signal) and nothing came up. Blank screen.

I have worked on a number of two-wheelers but have not tore into this tryke much as of yet. Any ideas or suggestions? Has anyone seen this before? I looked through the forums and nothing jumped out at me.

Thanks all.

Fuel filter? Also check the vacuum hoses on the throttle bodies and the rubber boot between the throttle bodies and the engine.

I'm guessing that the vacuum hoses are the culprit... At six years old: they're more than due to be replaced.

It's time to do both the fuel filter and vacuum hoses. So, while your in there, you can give the throttle body boot a visual inspection.

Visual inspection is the best you can do like others have suggest. Check out for loose wire also. Good luck and let us know.

My 2010 Rt did the same thing as you described and it was cracked vacuum hoses. Once I replaced them no more problems

+1 on the vacuum hoses. I had the same problem, and both hoses were cracked all the way through.

If it is the vacuum hoses make sure you replace them with Silicone tubes as they last a lot longer than the stock hoses. Also make sure the new hoses are the same length as the old ones.

20150726_160929.jpg but if you bend them you will see the cracking and this is where the leaking begins. Replacing the fuel filter is a good idea as well debris collected can be shuffled on bumpy roads and decrease the fuel flow....
