Help needed on BMW HP2 Sport - engine problem

[Chantank]

Dear all, I have a lingering problem which haven't been fixed for sometime now on my 2009 BMW HP2 Sport A little over 6 months ago & out of no where, the bike's engine starts to have erratic behavior from un-smooth running. I took it to a first BMW dealer they found no problem, I believe they tinker with it a bit but sure enough within the 2 day of return things got worst to now what I'd call engine splattering which is unridable. The bike would start but the engine runs so erratically it eventually stalls to a dead stop. I called a 2nd dealer with some hope but they told me they have the same year bike with same problem sitting here over 3 months & still can't fix it. Does any of the HP2 owners have some ideas for me? Is this a common problem? What's options are there to fix this? As the local boys seems not to have a clue. Thank you all in advance Note: I also posted on another site as I'm in desperate need of help. Kris

It could be as straight forward as an intermittent stick coil.
If you could borrow a known serviceable coil, then try it on each cylinder to fault find.
To perhaps give a clue before hand, start the engine and use a temperature probe on each side.
HTH.
