Few things to check here. I had a similar issue and felt very stupid when it was solved. The battery terminal was not 100% tight so it would intermittently lose connection and stall out. I would first check that your battery is good. The sled absolutely needs a good battery to run. Next I would check the TORS cable adjustment. If it is too tight or loose it will cut out the sled as a safety mechanism. Lastly I would change the plugs, they can get easily fouled but are not the most enjoyable thing to change out on these.

Check your battery TEST it. I just took out the original battery - it seemed Ok but it started and died 1 or 2 times before it would idle. With the new battery it pops right off! Original battery was over 9 years old.

Brand new battery in it . Took it out today started right . Let it warm up to have way took it 100ft and it stalled ..... would not restart threw a code p1338 crankshaft sensor spike ??? Could the crankshaft sensor cause this ?

It's going to the dealer tomorrow. Hopefully they can fix it

One thing the dealer told me about the error codes is that they are not stored, and it basically will flash whatever is causing an issue at that exact moment. Meaning, a fuse or relay could be bad causing poor electrical issues. The crank sensor might not be bad, but that is the resultant issue at that moment. Since mine was the battery it was causing multiple intermittent issues. With a new battery that is odd for you.

Yeah thanks for the info viper_dean the dealer tested the crank sensor they can't seem to figure it out

 

[yamahartx]

It's gota be able to be fixed.
Could it be the throttle position sensor or ground wire somewhere...
It's throwing some different codes crank sensor spike detcted crank sensor tooth not detected. Tps sensor. idle air air circuit.

I had trouble similar to yours and found it took awhile to run that crap gas through. Changed plugs and used a high quality injector cleaner, fixed the problem. I change the plugs every year. It's a cheap maintenance thing. Plugs do go bad on a four stroke sometimes.

 

[yamahartx]

Well it's had 2 sets of plugs this year so far and keeps fouling them up . I could be the old fuel is still in the line. Almost thinking a ground issue or ecm ?

 

[yamahartx]

Yamaha dealer diagnosed the ecm as the issue . Got the sled back drove it 20mins and it quit again .... p1338 code came up I'm loosing my mind here !!

Did they replace the ECM or did they just tell you its causing a problem?

 

[yamahartx]

They replaced the ecm they claim that it was the problem not totally convinced of that though .
