Was going to post something up like this unitl i read your post! My girlfriends pop keeps playing up too, basically we drove it all the way back from essex the other night (around eighty miles) fine without no problems, pull into my drive turn it off for a couple of minutes then start it go to drive off and it cuts out. So we tucked it in for the night and left it till the next day. The next morning starts up fine and drives for about 10 miles and cuts out, we left it for ten minutes and tried it again and it fired up and drove home no problem. This happens every time we take it out and im thinking its the manual fuel pump. Anyone had this problem on the old side valve engines?
