its almost always a ''ground'' issue who create weak spark, clean all the grounds wire every season . (it can be a bad battery who is ''shorted'' and ''pump'' all the current) , its an electric problem or in rare case, mice nest in airbox :0)
Check the fuel pressure by routing the return line to a bucket and starting the sled, if there is no fuel try the high pressure line and jump the pump with a 12 v battery, if you can easily stop the flow you could have a bad pump OR somewhere down the line there is a crack cause loss of pressure
Check your smart valves in your gas tank. You will find they are collapsed causing lack of fuel to fuel pump If you run to long in this condition you will damage your fuel pump cause it is running dry
I have an 04 Mountain Cat 800 efi (600 miles) and I'm having a similar issue...but it's fine for the first few minutes or so, but then gets worse. I cut the tss, maybe it's the tps? Maybe power exhaust valves?
04 Mountain Cat 900 that would go limp mode almost as soon as I went off idle. Spent a very long time chasing this same kind of issue. Pulled stator, injector service, wiring check, different injectors, regulator, tts delete and new coil only to find out in the end that it was the tps. Put on a used throttle body from an 800 Mtn Cat with my injectors. I'm pretty certain that SP1 will have a replacement tps for your 800 as I did see one for mine.
Thanks@@philhaughn6537 yeah, I cur the tss, and it seemed to solve a bit of the problem...but noticed it still has a tendency to bog out, and I think you're right with it being the tps.

Its your TSS. Throttle safty switch. They get worn out. You need to unplug the 3 wires to the throttle.
It has been completely bypassed, I'm certain it is the TPS.
So if we disconnect the 3 wires, can it get rid of the bog? Or would we need to get another tps?

Did you ever find out what it was? Having the same issue!
How do you ohm it out
They come with a jumper plug in with your tool kit ...

Can we convert EFI to carbs without replace cdi box ?
Or ignition timing trigger out of range

Mine does it till it shuts down every time it acts up
Hi, do you fix it?
Yes, it was the TPS sensor. There are a few more videos on my page that may help you out
Great video though!
You ever figure it out?
Not at the moment. I have not gotten time to install the throttle body yet.
@@KingSalmon thnx Sam for responding back
Tss switch is bad
