94 Verada/Diamante - Stalling Problem - Any ideas ?

Hi,

Has anyone had any experience or knowledge of what is causing my
Verada/Diamante to stall ?

Bascially I can drive it around for 5-10 minutes (longer if there are
no stoppages or idling eg traffic) and then all of a sudden the revs
drop and the engine stalls when I brake (or slown down without my foot
on the accelerator).

I had the car serviced and the mechanic of course couldn't repeat the
problem. He adjusted the idle controller and checked the engine
managment computer for errors. There were no errors stored in the
computer (which he said is unusual). Anyway he ultimately said he
wasn't sure what was wrong.

The common link appears to be a stoppage after about 10 minutes of
drivingn - but not sure if this is directly related. I managed to
drive around the neighbourhood for almost an hour with out the
stalling occuring, but after I stopped at the service station to pick
up some things and left the engine idling for a minute or two the
stalled then occured just after I started driving again.

Thaks

Jason.
