Close to running out of gas .put $20 in it started spitting sputtering and dieing.changed plugs cap rotor .still the same .Changed the inline fuel filter it worked like for 5 miles it ran good.then it started again.Could it be bad gas or fuel pump?

I would check the fuel lines themselves and make sure there is no blockage. If not you might want to check your fuel injectors and see if they need to be replaced. also make sure you didnt install fuel filter backwards.

Hey there boatright33,
A few things things immediately come to mind.
There may be a problem with the engine controller. You could check the
ODBII onboard diagnostics. Auto part stores will usually do this for
you at no cost.
When you pulled the ones that were/went bad, how did the filters look? Could there be particulate matter still in the tank causing them to fail.
I always put this one off until last. Check the injectors. Are they gummed up?
Let me know what you find out
Mike

It has to be done with a scanner. You can adjust this distributor, but there are no timing marks to watch as you move it. There is a timing mark on the balancer and on the timing cover for referencing Top Dead Center #1 cylinder only, but it is only used for dropping the distributor in to get the engine up and running. A scanner is needed to properly adjust the timing. Connect the scanner and look for a data parameter labeled ‘cam offset’ or possibly ‘cam ******.’ It will be listed in degrees. Start the engine, and bring it up to 1500 rpm. Note the reading. If the timing specification is not within plus or minus two degrees of zero, you need to move the distributor. You can move the distributor with the engine running but the timing will not change. After you move the distributor, the ignition has to be cycled off to let the computer learn the new timing spec. Restart the engine, bring it up to 1500 rpm and see what the new spec is. You must repeat this procedure until you get the timing into the specification as mentioned above. Once you have it set to spec, the code should clear.

Did you check the fuel filter?
or possably the catalitic converter is cloged, check the exhaust pressure.

that has a votec engine in it the fuel pressure is droping at knight and it takes 60 psi before the injectors will fire most likely cause fuel pump ,leaking injector ,or a feul pressure regulator
