Question Turns off while driving

I'm new to this.
Need help
My 00 Disco ll didn't turn on after driving it about 7 miles.
It wouldn't crank over as if it didn't have any fuel. And after 15 mins. it turned on. And within 10 mins. Of driving it back home it turned off. I let I sit for another 10-15 mins. It turned on. And I as soon as I arrived at my destination it turned off again. I waited another 15 or so mins. To see if it would turn on. And it did.
Can it be the fuel pump or the fuel pump relay?
Please help

That is your crank position sensor going out.

It is under $100 bucks and a pretty simple fix (an hour or so). There are plenty of "how to" threads on here with pictures to help you out. It's only a few bolts to remove. The hardest part is getting your arms up in there to plug and unplug the sensor. When you install the new sensor, remember it goes sensor, then spacer, then bolts. Some people have put the spacer before the sensor and that will not fly...

Thx for the info. I'll replace it and hopefully that will knock out the problem.
Another question. How and where can I check for fuel pressure?

There is a test valve port on the drivers rear corner under the top intake. Very hard to get at. #9 in attached page from RAVE shop manual.

unplug the sensor from the top, there should be enough wire when you go to unplug it.
