apologies for the lack of car knowledge its really something i don't know a lot about. I have an m reg ford escort van which i drove into work on monday morning. when i decelerated to stop at a roundabout the engine smply cut out and took a few attempts to start up again. this happened again at the next roundabout - i broke to a halt from about 50 mph and it cut out again. this time it took a good 4-5 minutes to get started again.
i took the van to the garage and they suspected an air lock or air leak
- i can't remember which exactly. the mechanic had the van all day and found nothing wrong and took the van for a drive and said it behaved perfectly. it was fine all day yesterday but this morning it cut out again at the second roundabout it cut out at on monday. ideally i'd like a few ideas as to the cause just so i know which direction to point the mechanic in when i take it back - or if its something obvious so i know to take it elsewhere!
