Running half power FI light on.

I'm having a problem with my 2008 kawasaki brute force 750 ever since I let it sit a little bit. The next time I started it up it conchs out when giving it gas. Sometimes it will stay revved up and back fire. The quad will only go around 20mph for 30 minutes then the motor cleans out and runs like it should for the rest of the day.

The FI stops blinking once it clears out and runs fine. The process repeats itself the next day though. I replaced the fuel pump. This atv has a dynatek computer and the motor has 300 miles on it. I did the diagnostic jump and it's hard to tell what the code is because all the flashes are slow unlike the help videos where if the code was 14 the 1st blink would be slow and the second 4 would be quick consecutive blinks.

Any help would be greatly appreciated.

Start by checking all the electrical connections especially the ones under the fuse box. How long is "let it sit a little bit"?

It sat for around 3 months. Once it runs for around 30 minutes it run fines even through rough terrain. If it was electrical wouldn't the quads performance be more inconsistent where hitting bumps would knock its power in and out?
