starts and then stops!!!

Hi.
My rd350lc starts fine from cold, but you have to rev the nuts off it to get it to move off and then after about 3 or 4 minutes it stops and i just cant get it started for ages again. Yes i know its tricky to say what may be the problem, but can anyone give me any suggestions as to where i should start looking please?
Cheers.

Was it running OK previously? Whats changed?

Only an idea but have you checked your exhausts are clean inside? If they are clogged it will definately affect your bikes performance due to screwed back pressure and it kinda fits in conjunction with the engine dying when warming up.
Good luck
