Car statred running bad suddenly

I will post here until this problem is solved. I checked my fuel pressue and running just like yours around 28 psi at idle. If I remember correctly this is good. During acceleration I get a jump just over 30 psi. However, when the car starts running a little rough I notice the pressure going up initially to 30 but dropping down to around 22 psi. Not sure if this is the problem. Just data for reference.

To all, I went to the Pittsburgh Grand Prix car show on Sunday, it was about a 13 mile trip each way and I had no problems at all even in stop and go traffic. This is with the new fuel filter. I am inclined to think, and crossing my finger's that it was just water. I will find out eventually.

I want to thank everyone for the help.
