Check the vacuum lines first. Make sure the air duct is secure to the throttle body. Check the EGR system. All of these are vacuum leaks. Will cause rich burns. After that check codes. Cold be MAF, MAP, O2 sensors. Could also be the injectors stuck open. They would need cleaned or replaced.
Get the OBD codes read as will be a switch/sensor causing the problem , codes will tell you which one(s)

I believe the codes are emmission related. I would have the fuel pump pressure checked. The fuel filter and fuel pressure regulator seems to be the failrue. The restarting of the engine several times is making the system build up enough pressure to start running . I would take to a shop to have the fuel pressure checked.

THESE ARE FROM THE GM CODE DIFINITION MANUAL, U NEED TO TAKE THIS TO THE DELAER, U HAVE SOME SERIOUS PROBLEMS TO GIVE THIS MANY CODES.
P0300 - Engine Random Misfire Detected
P0441 - Evaporative Emission Control System Incorrect Purge Flow
P0705 - Trans Range Switch Circuit
P1106 - Manifold Absolute Pressure (MAP) Sensor Circuit Intermittent High Voltage
P1133 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1
P1441 - Evaporative Emission (EVAP) System Flow During Non-Purge
P1662 - Cruise Lamp Control Circuit
P1672 - Low Engine Oil Level Lamp Control Circuit
P1870 - Transmission Component Slipping

Just because you cant feel in doesn't mean it isn't slipping. The computer monitors input rotation speed and output rotation speed of the transmission. If the output isn't within a certain range the computer stores this code. The only reason for this is transmission slipping and will require a rebuild.

I had this same problem on my 2005 monte carlo, took mechanic a while to figure out it was the idle air control valve. They also replace the idle air control motor.
