my van died going down the highway 60 mph. it will start and run for @ 15 min. then die. start and run til you give it gas then it boggs out. I had to have the egr valve and fuel filter replaced @ 1 year ago. you can hear the fuel pump kick on when you turn the key on. I can't get any one to agree on them problem some say fuel pump some say the throttel body I just don't have the money to replace this that and the other. I just went through that with the alternator and stater and battery. Please help.
