I just went out and put a fuel pressure gauge on mine. Turned the key forward and jumped up to 48 psi and a full 2 minutes later was still above 40.
With this being said, did you have the problem prior to the swap to the Accels? I've got a friend that just had brandnew Accel 48's and one was bad. You could disconnect the cold start after starting, and see if it makes a difference upon hot start. I'm leaning towards one of the new Accels going short to ground once it warms and flooding.

The cold start injector is controlled by the cold start thermo switch on the front of the intake manifold. It is powered by the starter solenoid and only gets power while the engine is cranking. It has a thermal element inside that times out after 8 seconds. It also measures the coolant temperature and will not turn on if the coolant is over 95°.

The ignition control module is responsible for sending the reference pulse to ECM. Without the reference pulse, the ECM will not fire injectors.
The module may fail when hot, so you need to check with a noid light or the test I mentioned above, to see if fuel is being delivered.
