Was in traffic my car just cut out, restarted straight away didn't think much about it.
But today I took it out and happend twice mid driving.
Drive home checked hoses and anything loose but all is ok.
Drive out again and happened again, everything is new on the car, any ideas?

 

Have you tryed new fuel filter matey

 

Check your alt is working correctly and charging at a good rate
Does sound like a relay playing up

 

could also be poor tuning

 

Mine does this as well.. Since I've had it converted to EFI I would be driving along and randomly it would completely cut out, still not been able to work it out.
