Random appearing distortion while playing LPs


Hi
I have a problem.While playing LPs,i have a random appearing distortion that sounds as if the radio drifted off the station.The distortion appears not on every LP (today i encountered it on 3 out of 9 records i played)and lasts from several seconds to half a minute and on several occasions it dissapeared when i approached turntable.
What can cause this?
Turntable :Michell Gyro SEmkII,Rega rb 600 arm,Grado Reference 4mv cart.The phono stage is Pentagon (solid state ,as everything in my system)
overhang

I was thinking the same thing as Shardone.

do you clean your stylus and records before playing? That might solve this issue. FWIW I have had TT's in very dusty environments and found the same thing but if I clean the stylus and records before playing, I don't have this issue.
