Default Hard to Start/Sputtering problem

Im having this problem on my 1995 that just started a day or so ago. It takes about 3-4 tries to start up and if I give it more about half throttle she starts to sputter and pop and bog down. But it only happens sometimes. Would this be something with the fuel maybe a filter or a regulator or something more with a spark issue?

The first two items I would check would be the fuel pressure with a gauge to see if it is correct.

The second item to check would be the vacuum line on the FPR to see if it is leaking fuel back into the manifold. Pull it off and see if it is wet especially after pressurizing the system.
