I had exactly the same problem mate,turned out to be a dodgy earth,theres two earths next to the battery I cleaned the earth point near the headlight that the battery lead goes to and its been fine ever since yours might be the same

how did you clean it mate and sorry where are the 2 ? just follow wires from pos to earth and neg to earth explain thanks?

If you follow the negative lead down it goes down to earth points on the chassis leg which sit near the back of the headlight,clean the one thats closest to the battery the bolt will probably be seized aswell mine took a bit of getting off.i just cleaned the end of the terminal that the bolt goes through with sand paper and wirebrushed the bolt till it was shiny,not had a problem with mine since
