Default 2008 Trailblazer???

Ok Iím new to this but here goes... So I have a recently acquired a 2008 Polaris Trail Blazer 330 and Iím having a problem keeping it running. The problem 1) starts but dies after 10-20 seconds idle
2) will not rev up after starting, give throttle it dies
it however fires right back up

i have done this so far with same results
1) new fuel and lines
2) new carb and fuel pump
3) new carb boots and air cleaner
4) new spark plug nice bright blue spark
5) I scoped the jug with a camera and looked great, has good compression, valves looked cleaned inside
6) new battery

i felt it was a fuel issue however Iím thinking maybe electrical?

make sure the etc has slack in the cable at the throttle to eliminate the over ride kicking in.

ETC checks out good works as it should, I got some feedback on the air box being temprimental. Cleaned all seals replaced boot and still starts runs then dies.

It needs, fuel, air, spark, and compression to run. If all those all check out I think timing would be next on the list to check. If it's a cheap aftermarket carb that can be a problem too.

what happens if you are choking it while it starts to die or rev up? trying to see if it's a lack of fuel issue

If itís choked or not it starts right up but wonít rev up or change runs like 15 seconds then dies. Now yesterday it started and ran until I tried giving it gas. Itís just like nothing allowes it to rev up.
