Hoping someone here can help me, lol. I Have an 06 Monte LS, standard everything. Lately it has been having an issue where i will be driving down the road, and if i turn my blinker on, or turn on my brights, the entire car shuts off and turns back on again. It all happens faily quickly, turning off and back on within a second or so, and most times doesnt cause much trouble. However today, as i turned into my local fast food place, turned on my blinker, it shut off and turned back on like it has before, didnt cause any troubles. But as i was exiting the drive-through, turned on my blinker to turn onto the road, it shut off, but didnt come back on immediately like normal. it stalled out completely as i was in the middle of my turn onto the road. Had to put in park, turn the key off, back on and restart, which it didnt wanna do right away. But it started back up after a second of turning over, and away i went, luckily no oncoming traffic was coming. So hoping someone here can help me narrow down why this might be happening. I was thinking it might be a short somewhere, but i dont even have the slightest idea where to begin looking. Most recent work done to the car wasnt even really work, just that my horn had not worked since i purchased the car, so i had pulled the headlight assembly to inspect the connectors, put it all back together and horn was working. It was shortly after that that this problem started happening. Anyone have any ideas?

Edit to also add that this problem doesnt happen EVERY time i use my blinker or my brights, but randomly.
