the seat has a new pwoblem.. a few times now in the past month or so, i'll be driving around for 10mins and then while sitting at the lights idling in neutral.. the car just conks straight out. it doesnt seem to struggle then die.. just dies straight away. it then takes a few goes to get it running again. im still only putting 98 into it so i assume the engine would be alot cleaner than all the cars running ethanol or normal unleaded..

any ideas?
