The car will not crank and when it does every time you hit the gas pedal it acts like it wants to cut off
Disconnect the mass airflow sensor located between the air filter and the throttle body. if it runs better that way then the sensor has failed.if it runs worse that way, then check your fuel flow and pressure.I don't know which engine we're talking about, but if it doesn't have a MAF sensor then it has a MAP sensor which is hard to diagnose without a proper diagnostic computer, but you can see if the vacuum line going to it has fallen off or is cracked and leaking.Both sensors are quick reaction sensors and can be the cause of your symptoms.

Did you check the fuel pressure at the fuel rail? with key in the on position to activate the pump? If you did and there was no pressure I would first check for the obvious, gas in the tank, leaking fuel from a line, check for flow before the fuel filter, located at the rear of the vehicle near the gas tank. take the fuel pressure line off put it in a catch can and have somebody turn the key to the on position to activate the pump, if it flows chances are the filter is plugged. Also pay attention to the sound of the pump if it is very loud there is a good chance the pump is failing and needs to be replaced. It could also explain why sometimes it dies. The pump is going out of range. Hope this helps

This is Caused by the Fuel Pump. If you remove the Fuel Pump relay and it will try to Crank, You have a Bad Fuel Pump. I do Believe that the Fuel Pump is located inside the Fuel Tank on the Sunfire. Not an easy Repair But, Necessary
