Have a Mac Pro 15inch mid 2015, the battery health info condition is normal & it has a cycle count of 715. It cuts out at 50% battery, when i reboot with out hooking it up to the power it comes up with the battery symbol saying it's out of charge but when i hook up the power cable again the 50% battery amount comes back? All my system checks are telling me that the battery is not the issue here.

Ok so it's saying the battery is 'normal' & the cycle count 715, you should be able to get a cycle count of 1000 normally before it starts asking for a battery replacement so i'm a bit sceptical. I ran an apple diagnostic for the(power on self test) & it passed but will get the battery check out with apple, thanks for your help.
Not necessarily. The battery health and "normal" operation is an estimate. I've actually seen battery status in a Mac bounce several times from "Good" to "Service Now" before it was replaced (after it started swelling). Premature failure isn't necessarily reflected in the diagnostic status.
Batteries will age just with time and not necessarily with use. Also - not all "cycles" are the same, but it's just melded into something easier for the user to understand. I've had an OEM Mac battery that was indicating about 94% battery health out of the box and that wasn't below 80% even after about 6 years and less than 100 cycles. It eventually failed (couldn't power it on) but then came back to life indicating about 70% battery health. It had less than 150 cycles reported.
1000 cycles to 80% battery health is just a design goal (with nice round numbers that's shoehorned into dozens of different batteries), but it's not a guarantee - especially not when out of warranty. I've seen OEM batteries in Apple devices that vastly exceeded Apple's ratings, as well as some that went out prematurely. There's a certain randomness to it and that's unavoidable with current battery technology. It's really all about averages. Some will be above average, some will be below average, but many will be right around the average.
At this point you might stand a good chance of getting a replacement from Apple at their standard cost (should be $249 in the United States). Otherwise it's likely more than 7 years since it was discontinued, but Apple says that they have up to 10 years.

From your description, it sounds like that battery is spent. End-of-life failures happen in a multitude of ways, and that is one of many.
A new one from Apple runs about US$250 installed and warranted for 90 days, provided nothing else is wrong with your computer.

Unfortunately i have tried this already & the fault is still there.
My Mac pro battery cuts out at 50%, have to hook the power cable again then the 50% comes back
