Car starts but stalls in under a minute almost always. Sometimes runs a little bit longer but still dies. What could cause this?

Scan for codes and check fuel pressure with a gauge clean throttle plate on both sides and iac hole with choke cleaner.

No codes show up cleaned throttle body IAC egr checked fuel filter and pressure. With pressure regulator plugged in it holds 32 psi with it unhooked it holds 40 psi

Fel pressure should be 35-45 psi and is low that may be the problem. Check for a vacuum leak as well especially if a hose goes to map sensor.
