Default Cranks and Idles fine for a second then sounds like **** and dies

Been battling this issue for a few weeks now.

Fuel pump primes then car cranks and idles just fine. Then after a few seconds car begins to sputter,hesitate and die. If i give it any gas it bogs horribly and usually dies.

Things done:
Replaced Coil
Replaced PIP
Replaced TPS has less than 1v when accessory
Replaced 02 sensors
Replaced Fuel Filter
Fuel Relay pink/black wire has 12V
EGR is deleted
While running unplugged IAC and started idling worse so assuming that is good
While running unplugged MAF and started idling worse so assuming that is good
Fuel Pressure Gauge reads 30psi when off. When on gas is pressed increases pressure as its supposed to but bogs

What's blowing my mind is it idles good for a few seconds HELP!

What is the fuel pressure when the car is running ?

Pull codes before throwing any more money away.

Post back with what you find.

Good luck, and Welcome to the forum.

Are you sure you pulled codes correctly ? Some of those aren't making sense.

There is no code 10 or 8, and a code 11 means everything is fine. You have a code 12 listed twice. The codes do repeat if you let them if that's what you saw.

Here's a link for understanding the codes, and just out of curiosity, have you ever done a "Base Idle Reset" ?

Oh, and as for the fuel pressure, does it fluctuate ? It should hold a steady 35-38 psi at all times when engine is idling. And vacuum line off. Pressure will rise a bit with vacuum connected.
