Welcome to the forum!

Sounds like your diagnosis is probably correct, sounds like the symptoms of a weak fuel pump. One test would be to cycle the key a few times next time it acts up for you. When it won't start, turn the key off for about 5 seconds, then turn the key to run for about 2 second, back off for around 5 seconds, then on for 2 seconds, off for 5, then try to start it. If it starts up just fine this way, your fuel pump is probably due to be replaced.

The fuel pump is an electric motor and is located in the fuel tank. When your first turn the key to run, the pump should run for about a second to prime the fuel rail. As the pumps wear out, they don't fully prime the fuel rail. Multiple primes typically work.

You could also check your Key On, Enging Off (KOEO) fuel pressure if you have a pressure guage.
