Sounds like it may have two problems or one which shows in two ways, so it will take a bit of looking to sort out. I would first look at moving the wires back where they belong and while doing so, look for damaged wires in the bundle. Second I would have to find the cause of the GFI failing. Always keep in mind that a new GFCI can also be a bad one so checking for causes is usually more direct.
A meter will show if there is a good hot, neutral, and ground on the GFCI coming from the source without the GFCI or downstream wiring connected. If good to that point, add the GFCI and find if it is good and will stay rest. Once input wiring and GFCI are verified, add more wiring and equipment to the circuit to find what is bad.
Breaker will not be likely to be a cause as it is what supplies power to the circuit and pretty well has to be good for the GFCI to sense a problem and fail.
