    I have exactly that kind of issue with my 2004 Suzuki Rm85... :\

    I'm currently running a BR10EG plug, i think this may be too cold of a plug, so i want to get a hotter one because you have the same problem as me...

    i start it, starts instantly (when plug is cleaned) and then 1-2 mins of running, i have to keep it alive but it just dies... :-\

    the other day i had some luck, i cleaned the plug (Perfectly!) and i plugged it in proper tight and it kicked and ran.. 1/4 throttle it was boggy and dieing... but as soon as i keep it over 1/2 throttle it ran sweet and i got about 25 mins of messing around and havin fun... but then later on, i wanted to show my dad that it ran and it wouldn't... had the same damn problem... starts and fouls (dies..)

    If you or anybody has any ideas, plz help would be appreciated.
