92 mercury capri - engine bogging

I have a 92 mercury capri - it starts and idles fine but when it warms up in about 15 minutes the engine starts bogging down. It will pick up rpm real slow but if you just press on the pedal the engine bogs and dies. Once it is warm it has trouble starting. I'm not sure how to go about checking the fuel pressure or exactly what it should be. If it's not the fuel pressure what do I need to check next?

My old talon started to show signs of bogging down so i started using good gas 93 octane and bought a bottle of fuel additive for cleaning fuel injectors. You could also check your spark plugs to make sure they are good to go.
