I have a 2008 700 trv efi, starts and runs for 15 minutes the dies, will not restart, let it cool down for 20-30 minutes and it will restart and run for 15 minutes and the dies again. Feels like its running out of fuel. Installed new fuel pump and it still dies. Has anybody else had this problem, the atv only has 623 miles

 

Could the fuel line be to close to a heat source and getting a vapor lock in the line? I have had no problems with mine.

 

You need to know if it is lack of air, fuel related or spark related so my first question would be: immediately after it dies does it still have spark? Second question is if it does have spark and you crank it a little bit is the plug wet? Third is it getting enough air (or too much)?

The other thing is it could be computer related as it is fuel injected. Which needs to be hooked up to a computer to be properly diagnosed. So if it were me I would eliminate any possibility of it being electrical or air related and then check for plugged, vapor lock fuel lines then take it in and have it put on their computer to be diagnosed.

 

Thanks for the help. When the machine died I checked the spark and it seem to be a little week, so I installed a ignition coil from a friends 700 and the spark seemed to be better. Rode the machine for a hour last nite with no problems. Installed the old coil and the machine dies after about 15 minutes. Thanks for all the help and if anyone needs a used fuel pump with 600 miles on it let me know
