Crank no start is different. Will it start if you continue to crank? It does seem a little like intermittent fuel pump.
Pull up your back seat (just lifts on the front edge) and with fan/ac and radio off listen for the fuel pump when you turn the key to on but not start.
It makes a very distinct whine/hum. It should last about 5 seconds and stop. You should always pause a couple seconds on "run" to let the fuel pump pressurize the system before cranking to get full pressure at the injectors.
If you don't hear the whine of the fuel pump then it's probably just that: when a fuel pump goes it can have a flat spot where it won't run but trying a couple times can get it past the flat spot. Once past the flat spot it'll run fine. (just at reduced power).
You can supply direct power to the pump by putting a jumper in the relay socket to rule out the relay and ECM sending the wrong signal.
