Yes, low fuel pressure can cause stalling. You can go to Advance Auto ro Auto Zone and they will loan you a testing tool. The test port is on the fuel rail and it is not hard to check. If you are geting any fuel pressure, the relay is okay. The suspect parts or issues are;
clogged fuel filter if applicable
fuel pump is failing
fuel pressure regulator is failing
other contaminants have blocked the line in some way.
The most probable, especially if your vehicle does not have an external fuel filter, is the fuel pump and sometimes the regulator will go bad. Fuel pumps are not hard to change and if you search the site you may be able to find an article on doing so. However, we are happy to walk you through it if it needs replacement.
Any Haynes manual will be more helpful though as it will have pictures that I cannot provide to you. I can only give you wiring diagrams.
The most probable is that the fuel pump
