A few months back I had a part throttle stumble. Every few weeks I got a P0190 code from the PCM. I replaced the Fuel Rail Pressure sensor and this cured the stumble.

A few days ago, I started the car and immedately the CEL came on. I pulled the codes and this is what I got:
P0190
P0193
P1233- Fuel Pump Driver Module offline

I searched on corral.net for this code since I have heard from Mustang guys that its common. One thread was started by a guy wondering what was wrong, he replaced his fuel pump with a SVT Focus pump and stated this cured it.

How many other boosted MM's are throwing this code and is it pointing to another issue?

I put a brand new SVT Focus pump in it Drew.
I believe the BAP is wired full time, so you might want to look into a modified FPDM from MJ Chip aka Mafterburner.com

It is possible from the codes its throwing that the PRVV in the tank is having a hard time holding pressure.

Have you heard anything about the FPRS disc that Kenne Bell sells?

These codes may also be related to the way I start the car.

I don't jump in and turn the key, I wait 3-4 seconds for the fuel pump to prime. I'll change the way I start it and see if it helps.

That disk is for stick shift cars that produce pressure spikes for those who cant powershift
