OK. UPDATE. So here is what the final verdict is after inspecting old turbos and all systems on car.
1. Confirmed, oil leaking on front turbo.
2. Fuel level sensor malfunction caused car to stop because car had no fuel.
3. Walbro 450 high flows from direct factory are NOT compatible with Precision Raceworks LPFP Stage 3 manifold - DO NOT BUY DIRECT FROM WALBRO - Buy replacement LPFP units from Precision Raceworks if you have their stage 2 or 3 or 4 kits. The Walbro factory units are not machined to fit the Precision Raceworks kits. I forced the install and the factory units worked for only 2 weeks then gave up because they had no seals for the PR LPFP manifold. There was a cut up o ring inside the manifold channel when I inspected.
4. The milky foam buildup in the Low Side Oil Catch Can was most likely due to the leaky front turbo seeping into the inlets and into the breathing ecosystem.
Note on Pure High Flow install: After installation, you may need to adjust your wastegate in MHD to silence rattle. This apparently in normal in Pure units and they have documented the need.
