I know that there are numerous threads on this issue and I have just spent the last hour and a half reading them , however, my bike seems to be stalling differently from everything that I have read.

I say this as last night I took it for a ride after 4 weeks of not riding it ( was in Italy for 3 weeks and oh by the way got a chance to go to see the MotoGp race in Mugello, very cool!!!, sorry had to throw that in there), the bike was working just fine for 45 minutes until I did about 10 minutes of in town slow riding and the temperature came up to 105 degrees Celsius or 221 degrees fahrenheit , once I came to a stop light the check engine light came on followed by a stall. I restarted the bike and had to rev it higher in order to not stall and to take off. i then came up on to some stop-go traffic where the bike continued to stall on me every time I came to a stop , I also did hear some snap,crackle pops when I was moving. The odd thing is that once I got away from the traffic and started to ride without stops and the temperature dropped to about 77 Celsius / 170 fahrenheit it wouldnt stall.

So when I got back to my house I thought that I would drive around my neighbourhood slowly to see if bringing the temperature back up would cause it to happen again and sure enough it did.

My valves and belts were done last fall and have since put on 3000kms/ 2000 miles on the bike without any issues, I cored my exhaust about 2 months ago and bike was tuned/dynoed with PCIII and have put on about 2000kms/1400 miles problem free since that was done!

The one thing that I did notice last night when I returned home and parked in the garage was the smell of fuel!

Thanks for your help!

Thanks Guys!!

Dennie, I have changed to a larger rear sprocket, 39 tooth, its been on for a year , no issues. coolant , recently done, battery cant see being the issue as it had tons of juice yesterday to fire up the bike every time it stalled.

I just ran it in my driveway on the track stand and everything was fine till the temperature reached 100 degrees , then it jumped instantly from 100 to 105 and 108 and at the same time the check engine light came on. The other thing that I noticed was that the rpms would fluctuate up and down.
I then revved the piss out of it and tried it another couple of times with the last time coming (check engine)on and only for a split second after I brought it up over 100 degrees the 3rd time.

I have a feeling that I need to check the fuel filter, air filters ( they were clean 3000kms ago) and possibly plugs unless you guys can think of anything else.

Thanks again!

Superfly, thanks for the error codes, will check to see which one comes up this morning. I spoke with one of the mechanics at Ducati and was told to make sure the fans both come on when it gets hot which they do. I then disconnected the PCIII and took the bike for a spin, NO ISSUES . When the bike was at hot temperature I plugged back in the power commander and the Check Engine and stalling issue started immediately.

This tells me that its something to do with the PCIII , I called Dynojet and they told me to check the wiring for any kinks as well as all the pins to make sure none were loose , they also mentioned with regards to the wiring to make sure it all has (or as much as physically possible) heat wrap around it .

I will check all this today to see what happens.

Last Sunday I went for a about a 200km highway ride , left at about 8am when it was cool, the bike with the PCIII ran beautifully , the tune and map installed by MAS Dyno (masdynoservices.com) is perfect. On my way back from my ride it was about 1pm and weather was getting quite hot , at one spot on the highway where they are doing construction the traffic came to a standstill and bike started acting up again. Goes to show that when the bike is moving and temp is lower it runs perfect , once it heats up it totally acts up.

Will keep you all posted on what happens, thanks for all your comments !!!!

Problem Solved !

So here it is ....

I find it hard to believe however, the overheating issue was somehow caused by the Power Commander. I unplugged it and tried running the bike without it , no stalling! I then contacted Dynojet , they told me to check the firmware version on my PCIII as it has been on my bike for over 3 years and is very possible that it has never been updated. I did in fact have an old version. I hooked up my lap top , saved first my map . Tried to update the firmware but no luck as the firmware version if I remember correct was 1.0.0.20 and locked it up. I then had to get my hands on Dynojets little programmer module and with that succesfully updated it, reloaded the map and runs like a top! Not only does it run perfect , I also noticed that it seems to run cooler , I had a hell of a time trying to get the bike hot enough like before to test it.

Thanks to everyone for their help and input. I f I can be of any help please do not hesitate to contact me.
