Yesterday for example, car started ok, I drive .5 mile and it stops, wait 2 mins starts ok. I then drive 6 miles continuously and then it cuts out when easing off for a road junction. Wait couple of mins again and up she comes. Did this another couple of times particularly when taking foot off the gas and putting it back on to no effect. Get home after 6-7 miles and it ticks over sweetly in the garage. Recently, before this problem, have replaced plugs, points, condenser so feel its not an electrical problem, suspect a fuel problem but I am a dimbo when it comes to carbs. Help welcome.
