Have a long story to tell but here is the short version. Had a Ford F-150 forget the year but had the same problem you are having found out what was happening after a week of head aches that the rubber gas line going to the gas tank from metal supply gas line that runs along the frame of the vehicle that rubber gas line was collapsing after running for about 5 minutes dropped gas tank low enough to watch as hose start to collapse and shut vehicle off and after another 5 minutes hose returned to its normal size. Strange but it happened. Replaced hose no problem since. May not be your problem but going by everything you have done already may not hurt to check it out.

Hey, ok.....I thought hose collapse in the back of my mind.....but......Now that I hear it, I'll check those hoses.....thanks...appreciate your suggestions. The mechanic is replacing the injectors, and since I haven't heard anything, I would guess it didn't work.....so I'll ask him to check those hoses. My fingers are "crossed" on your suggestion. Again, thanks.
