Replaced plugs and wires, fuel filter, fuel relay, fuel regulator, idle air sensor and MAF sensor and battery. It starts and runs but after about 30 minutes or so it stalls but starts again, runs for 30 minutes and dies, not sure what else to do. Please help.

You should get the fuel pressure checked and then if it is okay get the trouble codes pulled. Any Advance Auto or Auto Zone will pull trouble codes for free.

Fuel pressure is at 45 when it dies and I get no "check engine light" at all.

Even if there is no, "Check Engine Light" there can still be trouble codes. This will indicate any electrical issues that are out of spec.

I am going to give you a walk through for your issue. Just use the link below to get to it;
I am going to ask around some in the mean time. The fact that it sits and starts akes me think it is something electrical that is failing slowly and you might just have to wait for it to fail compleltely beforre we can find out what it is.
At least this will eliminate a few more possibilities.
