2000 gt ran really rough then died.

A couple of days ago I tried to start my 2000 gt. It really seemed reluctant to start which is weird. But on the 3 try it fired up and drove normally to the store. When i came out to leave it started right up but it was running really rough. I have had it happen before where it ran rough and i had a fouled plug so I thought time to change the plugs. I drove about a quarter mile and it became obvious that it was not the same fouled plug because it had no power. The more gas i gave it the more it wanted to die. So I pulled over and it died.
I had it towed home and changed the plugs which 4 of 8 were pretty black and the rest looked a little lean to me. It still did not want to start. not even a little. Fuel pump is pumpin and no codes. should i change the coils? any other ideas? I tried a search but did not find my exact problem and ones that were similar turned out to be coils.
Thanks.

I tried to get a code but there is not one and I just checked the schrader valve and fuel is spitting out. This is driving me nuts. Thank you for the ideas.
