I have an 06 Ranger 500 EFI. Last fall I took it Elk hunting in Wyoming. It would run for about 20 minutes then die when I stopped. It would not start again for 20-30 minutes. It did this over and over. I drained the tank and replaced with fresh gas. I pulled and cleaned the plug, it did have spark. I pulled the fuel line and it was pushing fuel.
Now it will only run for about 6-7 minutes and takes a good 20 minutes to restart.
Now I am getting ready for my elk trip and would like it to run properly. I don't like getting stranded in the mountains of Wyoming LOL.

Any idea what the problem could be?

Thank you for your help,
Kevin
