Vehicle start and runs for a couple of minutes then stalls

sounds like fuel problem but no doubt iam wrong again,firstly change fuel filter ,take it this motor is over the big pond because any self respecting europeon would have a vw or merc and if your poor a ford transit.firstly change the fuel filter or temp job blow it backwards with a air line ,then remove the fuel pump out the tank and clean the gauze filter on the bottom of the pump and look inside tank with a torch ,not an electric lead light?¿?¿¿?¿?clean tank out if it looks cruddy by using the existing fuel pump but stick a can on the engine end and then drain tank.Might find you have rust in the tank or somebody has put sugar in the tank or something stupid.Do you have many ex"s ?? .to clean out tank ,empty it with the fuel pump then remove the sender unit wipe it out the best you can with a rag ,then leave it to dry out for a day or so then push vacumn cleaner nozzle into tank and see how far you can get it round.Best of british mate
