after driving back from los angeles i stopped to get gas about 20 miles from home after returning to freeway my truck started to pulsate then it cleared up then when i exited freeway it pulsated again and died it started up and i was able to get it home where it died again,the next day i started it up and drove it about 10 minutes and it did it all over again so i bought some fuel additive and a new fuel filter but nothing seems to help it runs for a short times pulsates and dies let it sit a few minutes it will start but dies again the drive from my home to L A is 360 miles it ran great until i got almost home it seems to run good until it gets warm any help would be great thanks

first thing to do is see if there are any engine codes. then check your basics like ignition and fuel pressure. then take it to a pro who has done some work on these as the fuel injectors maybe messed up or the lines going to them as they had a tendency to break. Also check for a vacuum leak
