maybe so bad batch, id get a sample of the fuel into a glass bottle, look for water sitting on the bottom... it happens after a bad rain period... do this buy d/c the fuel feed hose and putting it into a bottle, get someone to turn the reds on, or even crank till u get enough fuel.... if there is water, removal of tank, cleaning will be required... also removal of injectors and replacement of baskets and a clean is a must, also usually fuel filter and pump is replaced... pray....
