Default Serious cut-out problem...

About a week ago, the motor wouldn't idle while cold. It would surge up and down 3k-250 rpms then cut-out. It wouldn't happen after the motor got warm. Now, it violently cuts-off almost like a sudden fuel cut out or ignition failure while I'm driving at random intervals.

I have just replaced the 02's, and IAC, and reset the tps. After it cuts out, I heard the fuel pump kick on and off at least 4 times. The starter solenoid is new too. I hear the solenoid trip but I haven't moved the key. The fuel pump seems to charge the lines just fine when I turn the ingnition.

Do ignitions do that when they go bad? The fuel pump is a aftermarket 255lph model that is 3 yrs old.

I am at a loss on this one...appreciate any input.
