can you replicate the problem at will?
next time you think it may do it...turn the key so the fuel pump starts priming,but dont turn it past that point for a couple of seconds.
it may just be low fuel pressure.
also...have you had the obd interrogated for any fault codes stored therein?

Have the BMW fault codes been read as 328mark mentions? it could well be a cam sensor fault, they are common on the m54 engine. You should also check the engine breather/vacuum and induction pipes out for any splits
