2000 Honda TRX400FW Foreman - what would make it lose fire when you take it above idle?
Just a thought without looking at it but could be loose wires involved with the coil. Bad coil wire.[burnt or worn on inside] Can you see spark jumping from pug wire. If so try tape on wire, and if that helps ,replace wire ,and coil if inseparable. Also check wiring coming from magneto, points or cdi . Electrics are the mechanics worst problem to solve.

2019 Polaris Sportsman 570 big boss misfire and loss of power over 10 mph
Could be fuel, fuel pressure, poor compression, spark, or air induction or other electronic engine controls.
Was it running fine and then not or has it progressed over time?Did it sit over winter and now has issues? Has regular maintenance been done, including scheduled valve adjustment?

1988 Polaris Trail Boss 250 4x4 ATV won't start?
Question edited for clarity, plus full make model (what it is).
Question moved to our only Polaris Trail Boss category.
That is a lot of stuff to change all in one go. One of those items has caused the issue in what was presumably a running ATV? Always best to swap out one item as a time and check everything runs as expected before moving onto the next, checking after each replacement.
The last sentence is confusing even with my edit. I take it you mean it turns over, it catches the odd time, but won't run. In that scenario, and with all the parts you changed, I would check the spark plug gap and that it has a good fat, blue spark. The other thing is the carburetor settings as per the service manual. Engines only need fuel, compression and a spark at the right time.
