Got an engine swap to the same vg30de model was bogging alot.. and would die every once in awhile when it was idling like at a stopsign. Then when I was driving home it started to bog bad going upphill got it to the house and it shutoff... I have not a clue what might be the problem.. the brake booster is connected to the prvr solenoid connection closest to the brake booster on the engine... please this is killing me I need help.. thanks

You've verified that there is spark? Easiest way to check spark plugs and injectors is by taking the CAS off, having a friend slowly rotate it, and check the components manually. Spark plugs can be grounded to the plenum to check fire, and you can use a long screwdriver up to your ear to check the injectors firing. See if those are good, and report back.

(obviously check for these things with the key in "run")

I had a problem similar to this.
The problem went away when I cleaned the connections on the Coolant Temp Sensor.

Many bogging problems are caused by vacuum leaks, do you have anything deleted like EGR or AIV? And what do you mean about the brake booster connection? There should be a 90 degree brass port on the side of the intake by the balance tube.
