Start with the basics...
The MAS/OVP/FPR whatever you want to call it needs to see and confirm a speed signal from the CPS/crank position sensor.
If it fails to see the speed signal in a few seconds it de-energizes the fuel pump(s).
This prevents fuel pumping into an engine that's not running.
It can be the CPS but more then likely the relay which is a very common problem.
Relay located behind the battery.
You can jumper pins 30 and 87 which energize the fuel pump and start the car.
If the car continues to run then it's the relay...
Your comment that at times it will crank but not start also points to the relay
