Its a 92 vanden with the 4.0. It reads fuel fail 11 and although it starts fine, the more it warms up the more it loses power. under acceleration it chokes up and once its hot it just dies all together. I've researched it for weeks and I can't find anything even somewhat helpful. Please help if there is anything you can suggest. I've never been quite so frusterated with any project. Thanks for your time.
