Aaron,
Try adding a gas drier, the stuff you pour into the tank, to rule out
contaminated fuel. Secondly if the problem still persist try replacing the
fuel filter. If you notice improvement; I would suspect fuel contamination.
Adding a quality fuel injector cleaner too would be in order.
Sincerely,
Mark Keller
