Thanks for blasting me. That wasn't necessary to be so dramatic. I'm trying to work with you not against you.
Fuel pump failure can most certainly be over a period of time and intermitant. It may be weak giving fuel presure that is low but present. As opposed to a "no volume of fuel ", it can have a "low volume of fuel. Conversely the fuel pressure may be too high ( fuel pressure regulator)
I brought up the possible sources according to Mitchell One. Since this is intermittant and it is your problem you want help with, you need to decide which way to pick at it. I gave you ideas and my recommendation to catch it. Since this happens approximately once every 20 days, testing may not be so simple as one pinpoint test.
An PCM is a powertrain control module, AKA a computer.
The reprogramming of the computer with the latest and greatest software may certainly be the fix.
This fuel system system is a returnable system.
Therefore the FRP sensor is not in the tank.
BMRFIXIT stated to "Check" the regulator first, not replace it first.
I apologize for not providing any help in my first response.
