| either
fuel filter - replace AND clean out the tank, condensation/rust/dirt in the tank is why it would be blocked in the first place and will do the same to new one. (most likey)
or
Injectors icing - It would have to be a very cold night - ad some Pro FST to the fuel or use optimax etc.. (pretty unlikely if it runs for a bit then dies)
or
fuel hose come off inside the tank (unlikely if it runs for a bit then dies)
No way of saying for sure but they are the best starting points.
Good luck |
