Im using these MPU-6050 modules from Amazon, and have soldered and wired one to an Arduino R4 Minima as this Instructable shows. And have uploaded the code below. It runs well for a couple of seconds, until it suddenly freezes at one value despite my continued rotation. What should I do? Thank you.
You might want to look at the schematic that's included on that Amazon page and see what Vcc is hooked up to on that module. And then take a very critical look at that Instructables page and see what it has it has Vcc hooked up to.
Try the sample code included with the library. If it fails then most likely the MPU6050 is toast. This is why we don't solder directly to an MCU. It may even have been over heating that caused it.
The wording in my first post may have been misleading, but I meant to say I soldered the header pins on and then connected them with the wires. And I tried powering it with both 3.3v and 5v, but they both have the issue of working well for a little while before freezing.
Edit: I used the Adafruit basic readings code, and it still froze.

If you know where to find Wire.cpp, you're likely at the level where doing this is a manageable risk. If you don't, you probably shouldn't be doing it.
