intermittent stalling issue

Ok....I've noticed in the last couple of days that every now and then ....when rolling off the throttle & pulling in my clutch....say I'm rolling up to a junction/ roundabout......the revs drop right off and she cut's out.
This has happened about four times in the last 500 miles......always when the engine has been warm,and seems to occur just after I have filled up at the pertrol court....weird?
Anyone got any ideas what may cause this??

1. Fuel vent hose pinched or clogged.

2. Dry and ube BGC.

Have your O2 sensors been switched off ?

either bgc or tps sensor not set quite right.

mine used to stall every now and then before i adjusted it.... now it runs like a dream and is much smoother.
