While driving the RPMs jumped to 6,000?

Hello, my issue is a bit odd. To set the stage I drive the car listed above, it's in good condition, needs an oil change and I will soon. I have had some issues, replaced a few parts in the evap system, had to replace a fuse, and had some damage done to the front passenger side that has since been repaired. Also had the turbo replaced.

So, I drive often, over 60 miles a day for 5 days a week. I am usually on the freeway at 80 MPH. Today was no different, I'm driving at 80, the RPMs at the tick above 2,000. Then all of a sudden it hits up to 6,000 RPMs. I can't accelerate and any slight push on the gas brings it up to 6,000. I pull over, start slowing down. I notice it doesn't seem to shift down, I try accelerating while going about 35 and still jumps to 6, 00 RPMs. I turn off my car, wait a few seconds, start her up again and the rest of my drive goes smoothly.

Would anyone happen to know what's going on? I looked it up and it might be a faulty fuse? I'm not sure what this is but I cannot afford a big repair right now. If it's a sign of something big I'd like to get ahead of it ASAP.
