Sounds like a typical throttle position sensor problem, ye before you get there check the air filter and make sure that youf fuel is not contaminated it is either your TPS or the air flow meter is going bad both are expensive sorry

Will start and Idle great but when push the gas pedal it just acts and sounds like its bogging down. I have replaced the fuel filter its a 1.5 4cyl automatic

You replaced your fuel filter but have you checked the fuel pressure. It sounds like the fuel pump is not putting out enough pressure to get enough gas to the engine.

I would suspect the fuel pump inside the gas tank is defective. Next time it fails to short hook up a fuel pressure gauge to the engine test port in the fuel supply pipe to the fuel injectors. You can buy the tester for about $25.00 on line.

When i push the gas pedal the bogs down almost as if i am out of gas

Could be several things wrong. One your fuel pressure may be low which means it could be a bad fuel pump. Have you changed the fuel filter lately? Also could be throttle position sensor. Does it recover after it bogs down? have you changed plugs or wires?

Motor bogs down at stoplight when pushin gas pedal

The fuel pump relay will cause a stalling or no start condition. You are likely having mass airflow sensor, fuel pump, or fuel pressure regulator issues.
