Hi my name is*****'m the side by side expert

Couple of things first, then we'll get started

  • Model code,if you are not sure then I can get it from the 17 digit frame number
  • Hours currently on this unit ?
  • Spark, do you know of the spark is going away ?
  • After it quits, can you here the fuel pump cycle ?
  • How long (estimated) time does it have to sit before it will restart ?

So when it dies it is like a light switch, or does it seems to sputters and then dies ?

Do you have the ability to test fuel pressure ?

Expert:  Kenny O. replied 1 year ago.

OK, I would like to try to narrow this down to a specific area meaning, if its fuel related or ignition, an easy check that you could perform is when the unit gets hot, spray starting fluid in to the intake, if the unit start or tries to start then we could pretty much relate it to fuel, if it does the same then it would have to be on the ignition side.

You have not got any warnings on the dash maybe indicating there is a problem ?

Customer: replied 1 year ago.
It is not giving any codes or the check engine is not coming on so I will that that when it happens again
Expert:  Kenny O. replied 1 year ago.

Try that to get an idea as least, so lets say that an injector is hanging open (fuel pressure will detect that likely) so the next time that happens, after you try starting fluid and it doesn't start, then they giving a little throttle as if it was rich or loaded up from a stuck injector, if then it starts then there is an issue with an injector.

I think you should be able to narrow it down, this is what they would do in a shop, the technician would have to at least get pointed in the right direction.

Let me know what happens !

Good lets try this first, one thing I didn't clarify with you when the unit wont start, have you actually verified that there is spark ?

Expert:  Kenny O. replied 1 year ago.

I just wanted to throw this by you, you have an intermittent failure going on, what's going is somewhat in your favor, meaning it will failure regularly when the engine gets hot. Usually when that symptom exist you look at the component that is related to excessive heat. With fuel injected units and also the with electronic ignition the common part is the CPS and is generally the culprit on most evasive failures. So go ahead and download the PDF file I created for you, you'll need a multi-meter to perform the test, ideally you need to test perform test when cold and then hot after the failure occurs.
