Fx450 problem

So I bought my Minted Fx450 all kitted out with 30 hours on the clock, I've now just racked up 55 hours never had any issue. Took the bike out for a spin today never had any issue the normal show off start of the Efi berg and off I went, stopped 5mins into the ride and adjusted my pants and went on again but after 2 mins the bike stalled crossing a muddy crossing, so hit the button right up it starts went 20 meters and stalled again! So go to start and its just no joy, its ticking over but its like its getting no fuel. I cleaned all the contacts that I could and then put the bike over on its side and start pressing the fuel lines in hope it would come back after 15mins of abusing the button the bike started. Was running bad and spluttery and cleaned its self out after a few mins but still was not running well. Eventual it started to run okay and I went for a easy spin to try "clean out anything" and started to work alright started to do some gnarly climbs bike over heated once and left it to cool down started no problem and then after 10mins over heated again and then could not be started after that had to wait another 20+mins before I got some joy.

Got the bike back to the van in the end got home unloaded and hit the button still not starting so opened the trottle full and closed it twice and it came to life, jumped on and rode 3 meter stalled and then back to not starting.

What could it be? I'm 2T minded this is my first 4T. Btw I was not cranking the trottle when trying to start the bike. I've never had this issue with my berg before.

A day now on and my bike starts, Dealer reckons its the Sparkplug cap and seen it a few times with the newer bergs I'm going to give that a go, getting the new one in a day or 2 with a new plug. After postin on ktmtalk they see it as a injector or fuel pump issue, I am looking to clean the injector anyway of doing this? Do you have to send them off or can you try clean it yourself?

I just remember something I might add to that. 2 days before this I was messing in the workshop fitting up my friends 520 Fmf exhaust to see if I notice the diff and the bike cut out on the stand when I fitted back on the standard, I had just washed it the day before but when I went to restart it it took a good min to get the bike started again. After that I just turned it off again and never started it till the sunday that this all happened.

Thanks for the replys guys should have my new plug cap tonight and few other bits so going to take of the tank and get a good look. I want to take off the tank as I have not done it yet and feel the need to learn a bit about the bike, felt useless when I could not do a thing when I was stuck.

Bike is priming alright, forgot to listen to it when it was not starting but I still think it was going to check that line though. No flash codes coming on just the Fi as you try to start it but then goes out.

Is there a filter coming off the gas tank or in the tank?

Ha the bike has not seen real Irish peat yet I've had no issues with my 10 over the 25 hours other than this, hope it will be the last though I'm sure I'll be back motoring at the weekend 8)

Going to check the fuel line and double check everything over, I must report back up my finds If I have any.

Just a update, Took fuel tank off and cleaned the lines aswell as checking over the wires everything A okay. Put the new plug cap on and the bike was running as good as new, I think the cap really did sort the problem. Never had 1 issue with starting today while all the other guys where gutted looking at me hitting the magic button 3rd gear pinned :bounce3:
