Hi jacky,
If you engine stall after let go the throttle - ISCV clog
If your engine stall while depressing the throttle - ECU faulty
Unproper hardness work can lead to this kind of problem after few months/years of driving.

Anyway, if you are driving a BT, its time to check your ECU now.
20's BT ECU has visited my clinic

the stall happen when slow down (let go throttle).. so it may be ISCV clog..
btw where is the ISCV located ?

after driving for about 30mins to 1 hour, try turning off and re-start the engine and see if the RPM is steady and the engine keep on running.. some clogging problems only happens when the engine is really hot.. just my 10 cent. all the best! :D
