Hey guys I just recently got a ktm 250sxf, long story short! The bike starts rite up, but when it heats up it’ll cut off, wait 10 min and it’ll fire back up, previous owner ran racefuel but informed me that running pump gas would be ok also! So I put pump gas in and it and started cutting off, while riding, dumped old gas out, filled with race fuel and replaced the small fuel filter... ran sea foam and still cutting off when it warms up! I’m also running engine ice, (topped off) changed oil, and oil filter, if I start it up and just ride it it’s fine with the exception of I have to keep Reving it when slowing down! I’ve also adjusted the throttle cable play?? Took it to dealer and valve adjustment was fine, it’s driving me crazy I’ve wanted a ktm so bad but it’s costing me so much money and time I’m ready to switch back to yz, can anybody help??
Sounds like an electrical issue..Have you confirmed if you have spark after it "cuts off"?
Check the fuel pump and filter too.
Also check the tank vent. If not working correctly it will reduce the flow of fuel. Then when it sets for a while it have allowed enough fuel to flow to run for a few minutes.
Check the coil OHMs on the primary side as it could be breaking down if that reading is too low.

OR just start replacing everything mentioned above all at once..
Free things...Test the fuel tank vent hose.
Test the coil.
Look at the fuel line to the pump.
Look at the fuel filter on the pump.
Check the temp sensor.

Sounds like injector needs to be cleaned, fuel filters also.
