Do any warning lights flash when this happens?
Ok, this is a very common problem on these engines, unfortunately there are several causes but many can be narrowed down so excuse all of the questions.Does the van restart instantly? And do you know if the fuel filter has been replaced recently?
Change the fuel filter before going further as many times i have seen this caused either a restricted flow or moisture in the filter which will upset the fuel pump. For something that is a service item and no history of the last change its well worth doing either way and only costs around £10.
Cam position sensor or crank position sensor will cause this, the crank sensor often wont show a fault code so again if the actual sensor has not been changed its worth considering the crank sensor. A Faulty cam sensor should show a fault code... but again worth keeping that in mind.Other possibilities are the Inlet Metering Valve, injectors or fuel pump. We can rule out injectors... and with the symptoms I think the fuel pump is unlikely so this would go to the bottom of the list.
Another possibility is the engine ECU, They are usually fairly reliable on these models but i have seen them cut the pulse to the injectors when part of the circuit that controls them starts to fail.. Again this is a last optionThe injectors should be tested with a spill of test kit, and the injector pulse should be monitored to see if there is an interruption in the injector pulse when it misses during idle. If there is an interruption the cam and crank sensor signal should be scoped to see if this is causing the problem, otherwise it leaves the fuel pump, ecu or metering valve.
Unfortunately some garages still don't have access to a diagnostic system with a lab scope, it may be worth talking to your mechanic... if he has one it will rule out a lot of possible causes very quickly which can save a lot of guessing.
