My car will start perfectly but when driving will lose power and cut out, but if I lock it the unlock it and restart it it's all back fine. Then it will do it again a few moments later, could be 5 minutes or 1 minutes later from starting. Only when driving this happens.

This sounds like the BCM is not working correctly, I would do a CAN scan to help confirm the issue, also you can get a preprogrammed unit by search google or eBay.

The unit sits behind the glove box, I would tap on it with the engine running to see if that affects the engine, this will help confirm the issue. Please let me know how it goes.
