2019 ktm 350 sxf running issues

Dannyderasmo106
Hey guys, so my 350 has 82 hours, last time riding it i just randomly bogged on me twice. Figured it might have just been a dirty air filter. Put a new filter, changed oil, tried to ride it, made it a half lap and cut out when i got the gas and kept stalling. It would start and idle but randomly cut out. Took home, changed the fuel line filter, checked all grounds, checked that the fuel pump was working. Tried to start it. It idled for 2 min then shut off and wont start now. Any ideas what it could be?

Don't see any mention of you changing the inline filter they need to be change every 20 hours. Also as mentioned above your fuel pump just because it's running doesn't mean it's putting out the right PSI,And after you check that the last thing I would look at is the TPS and also clean the injector if you haven't been changing the filters

I changed the inline filter. I can try to swap tanks with another bike and see if its the pump. I was originally thinking tps but seems strange that it was running and idling fine but now wont even start.

I did, also tried a tank from another 350 to make sure it wasnt the pump.

Try a new spark plug cap, if its cracked on the inside it causes all sort of problems like you are describing. I chased my tail for months on this.

Howd you figure out it was the cap? Can you see the crack?

Gotta swap it, it just screws onto the end of the wire, no tools required.

I would check the earth and positive feeds to/from the battery.
Particularly the positive connector block under the starter solenoid

Update, changed the spark plug and it seems to be running good now.
