88f-250 stalls every 3rd 4th trip

[lewis]

truck has 300ci fuel injected. only mid tank is used and it along with low pressure internal pump is new. replaced high pressure pump last week and it ran ok next two days. filter has been changed twice last time after high pump. just acts like out of gas than runs next day ok. has no stored codes and running codes show lean condition with coolant and air temp sensors out of normal range. both ohm ok and have 4.7 volts at plug. local ford garage is of no help. any advice on next step is greatly welcome.

Does your truck have a shraeder valve on the fuel rail?

Have you tried pressing it when the truck won't run, to see if there is any fuel there?
