I have a 2014 KTM 350 SXF. The bike starts up, but as soon as I try to give it any gas the bike starts to die. It sounds like it is getting too much/not enough fuel, but can't find any obvious problems.

I checked all of my electrical and fuel connections and everything seems fine so far. I also checked to make sure if the fuel pump works, which it seems to (when activated is sprays fuel out about a foot or so).

Any thoughts?

What are your TPS voltages at closed throttle and wide open?

Sounds like fuel starvation....
Check the inline fuel filter, fuel pump and injector for dirt or dried fuel.
These bikes are also known to have a fuel line kink issue inside the fuel tank that needs to be checked.

yea i would replace the inline filter anyway (black connector from tank to injector)

and check to make sure there isn't a kink as mentioned or a pin hole on the inside line

So far it looks like it was the injector. After cleaning the bike starts up and runs fine, but won't know for sure until I get to put some laps on it.

Thanks for the help!
