Weirdest electrical problem I have ever seen! Help?

Thanks for viewing my post and giving any input! 95 Ford Taurus GL 3.0L. So I was driving home today and went to turn on my turn signal while getting into the turn lane. The turn signal came on but it began to blink slower and slower as if it were dying. Then it didn't work anymore. No matter how many times I turned off and on the switch it wouldn't turn back on. Then, a few more miles down the road I tried to turn it on again and it work. It acted like nothing ever happened. Then again I got the same problem where it slowly cut out a few more miles down the road. Only this time, it has not come back on.

I checked the fuse. It's still good. I did a little playing around and noticed some weird things. As expected, when I turned the turn signals on nothing happens ( no lamps turn on). Then I tried using the turn signals with my headlights and brake lights on and now I notice that the lamps that are suppose to blinking are just off. They turn signal lamps turn completely off when I put my turn signal on. The same thing happens in the rear lights too. So, The lamps are obviously receiving a signal that they are suppose to be doing something. That would mean there isn't a fuse problem, a grounding wire problem, or a relay problem right? Or am I horribly mistaken? Any advice?

I would appreciate any advice or input you have with this weird problem of mine. I am pretty handy when it comes to the mechanics of a vehicle but electrical problems have always given me trouble. Thank you!

It's possible the flasher module is the problem. How do the hazard lights work?

Sounds like a bad flasher. I'm not sure about your Taurus, but my Escorts have separate flashers for the turn signals and emergency flashers.

They were not working either at the time. Craziest thing though, the past few days they have been working completely normal again. Along with the normal turn signals. I'm worried they may go out again though :/

Any time you see electrical problems that defy explanation it's almost always a bad ground problem. In your case, I'd bet money on it. Especially since it's so intermittent and works on some days and not others. That's a classic bad ground symptoms. Current can't complete the path, wires heat up, expand and contract and that's what gives you intermittents.
