fuel problems-5.7 EFI 1997-idles for awhile then starves for fuel and stalls.changed out I ak valve,map sensor,temp sensor,fuel pump and regulator,new intank pick-up and anti-siphon valve,new fuel hose to water separator and filter.sealed all water separator fittings and inspected for cracks.inspected all electrical conections.have any suggestions.
 
Definitely try a aux fuel tank first. My 5.7EFI did the same thing and after all the items that you talked about were checked and or changed it turned out to be a bad tank of gas was the problem.
