Leaking Coolant Mystery?? 700 1991

So I had a suspected fuel filter problem recently with the car dying at full speed on the highway, loud fuel filter and general poor performance. I replaced the main pump, FI relay, FP relay, fuel filter and fuel pressure regulator. Everything seems to be in order now and it is running 1,000 times better. At 268K I make it a point to park in the same spot at home and at work every day and look for possible fluid leaks. I noticed a small amount of coolant recently and then in the last couple of days I have noticed a large amount of coolant leaking and leaving a significant puddle. Of course this made me panic because I figured I either had a leak in the radiator which could be a major pain or there could be a small leak in a hose that could potentially be hard to find. I have been looking at the area where it is coming from and can't see a specific leaking point right now. I have been watching my temperature very closely to look for any possible overheating but in the last 4 days the temperature slowly rises and settles in the same reading that is has for as long as I can remember, just slightly past the halfway mark. I looked at my coolant reservoir and it is 3/4 of the way between min and max when hot. So what the heck is going on. I am losing fluid but there is no sign of it in the reservoir. The car doesn't overheat and has no problems to speak of. Is it the intercooler? I would have thought that if I had bumped a hose or damaged something when I was doing the fuel work I would have seen a drop in the level or some overheating. Thoughts??
