ISX cm2250 injectors?

[Shotgun74]

Hi everyone. I have a ISX 2250 550HP Demandated & about 61000 miles on fresh overhaul, 972750 miles on truck. The truck quit running while idling the other day & I got it to start again after priming (cycled the key about 4x) it started & ran fine to my unload destination. While unloading under high idle for pto pump it quit again. After priming it started up & ran for about 10 min. then repeat 2x to get the load off. It didn't throw a code but I could obviously tell it wasn't getting fuel. The fuel pump was replaced new in March 2019. I limped towards the home shop I use & it quit 3x on the way there this time giving a check engine light but would go out after 15 seconds or so & come back to full power while driving. We're getting champagne type bubbles in a bucket of fuel from the return line. (Picture) We pulled the injectors & they're passing a vacuum test. The one & only code it gives is (Injector metering rail one pressure low). I'm thinking injectors as they are all the original ones. Your thoughts? Suggestions?
