I’ve got a 2005 700 EFI with about 400 hours and 3000 miles on it. I’ve always keep it well maintained. Today, went up a steep, rocky, bumpy area for 30 minutes in 4L. Shut it down at the top of the hill, and after restarting, it started right away, but died after a few seconds. Many times. 80 degrees out, and dry. And then….ran just fine. Gas was 1/2 tank premium, non-ethanol. Plugs and battery good. Fuel filter and fuel pump never messed with. I’d appreciated any thoughts about what might have happened.
