5.3 swap, suddenly dies - The 1947 - Present Chevrolet & GMC Truck Message Board Network

so, I have a 57 chevy truck with an ls swap, has been running flawless for a while now, last night about 1 miles from my house it suddenly died, if felt like running out of gas, it crancks over but with start, the fuel is getting there with enough pressure, the ecm is getting power, the coil packs are getting power, I have to check the injectors getting power this afternoon, but other than that I am lost, it doesn't throw any codes, any ideas?
the ecm being used is a E67.

how did you check fuel pressure? do you have a gauge at the rails?
