Not exactly. It's not a problem with the pump, it's a problem with the bracket holding the pump (reserve cup being too small) and a bad gas tank that allows gas to slosh to the California side.

It's my first time hitting it off the track too, but this is my first time not being able to restart my car unlike a hick up like I had at the track. It's definitely not water, no sign combustion at the exhaust and you can just hear there is no gas.

Anyone who looks at the tank can see the issue. It is a fundamental design flaw that created issues for anyone who drives hard. It is not at all similar to issues like oil consumption, which is going to be hit or miss

100% agree.

I don't think it shut down the fuel system because there were a few times where the car "attempted" to fire. My best restart had me idling at 400RPM for about five secs. Problem went away as soon as I loaded it with gas. If I recall correctly, the fuel pump is fed by a combination of a vacuum tube sucking gas back in from the other side (no start=no vacuum). Correct me if i am wrong on this.

I hit the fuel starve at the track at 3/4 of a tank at 60mph. When I hit it last Friday, I never got past 70mph....

Otherwise you could be driving around with fuel in one half and the other half empty, leading to wacko gauge readings and fuel starvation.

See my response for Mike, it's a vacuum that sucks gas back to the right side, where the fuel pump is. The fuel sending unit is on the left side, hence the weird readings you get after hard turns sometimes. I also believe there is a fuel sending unit on the right side (correct me if i am wrong), but i am not 100% sure on that. The gas tank has basically 3 holes, one for the fuel hose nozzle, one for the fuel pump assembley and one for the fuel sending unit. If you want to do any physical work inside, you have to go through one of the three hole. This is why it is so difficult to get a fixed for us and so easy to do it at Nissan since they can simply retool the inners of the gas tank to prevent fuel from sloshing or redesigning the fuel pump bracket/reserve cup to make it bigger.
There is a guy that is supposed to be working on it, but it's been a while and I am not even sure if I want to spend $1000 on whatever fix either. If he doesn't come up with a fix, the shop that designed my trailer hitch will probably start getting into the car to see if there is any fix for it. I have to be honest, it's not going to be an easy or cheap fix, we probably have to wait for Nissan to send a revision to the tank or the pump or maybe a recall.....
