Default Sporadic temperature gauge... possible overheating/radiator issue?

2004 WRX

I went snowboarding out at Big Bear, which is about 110 miles away from where I live in LA. I noticed this on my way home. The first few miles when leaving Big Bear, you have to actually drive uphill a few miles before going down the mountain. After I started leaving, I noticed my temperature gauge going up a bit. As I kept driving, the temp kept going up, eventually into the red. I pulled over and popped the hood. It wasn’t smoking or anything. The coolant reservoir was full. After a few minutes, I checked the gauge again and it was back down to normal. I started driving a little bit, and shortly after I started going downhill where I could coast most of the way to the bottom of the mountain. Most of the time, the temperature went back down to normal. Anytime I had to hit the gas, pretty much anything over 2000 rpms, the temp would start going up again, but it would go back down to normal temp when I let off the gas. This would happen pretty quick, within a minute or so.

Once I got off the mountain and onto the freeway, didn’t drive aggressively at all and took it easy. It pretty much hovered at around the mark or slightly above it. Occasionally it would dip back down the normal halfway point. I drove it the rest of the way home like this.

Shortly after I got on the freeway, I stopped at a gas station. I checked the coolant reservoir again, this time it was empty. I filled it with water. When I got home, it was empty again.

Whenever the car is idling, it seems normal.

Thoughts?

pressure check your cooling system. check your oil for signs of coolant mixing. it has to be going somewhere...
