Default Cranks and dies question

2006 supercharged 408 stroker, kenne bell BAP, stock fuel pump. A few days ago it shut off on me after I cranked it up. I cranked it again and drove it 30 mins. Next day it cranks and dies, it has 60lbs fuel pressure when cranked, then when it cuts off it drops to 52lbs. The video shows what happens if i leave it in the "on" postion without it running. it will cycle the fuel pump relay and keep bringing it back up to 60lbs.of fuel pressure, the system will prime to 60 then it'll drop back to 52.. any ideas?

Good idea, I'll give it a shot. Yep I bought the car wth the BAP already installed. I thought stock pumps and BAP were good for 750whp?? I'm leaning towards bad pump being the car is 2006 and oem pump. BAP shouldn't matter out of boost correct?

Also it's only been boosted since 2013, so the pump has seen about 15,000 boosted miles

52psi is certainly not going to cause an engine to stop....or barely even change how it runs.

You have issues elsewhere.
