Maybe some wires got shorted-out. It’s been a muggy/humid day in the East Coast, so you might want to double-check your electrical connections. Inspect and clean them thoroughly. And see if the problem still there. Also, you might want to check and make sure the bolts weren’t juggled loose or something.

double check the ground connections also cause the may have over/under tightened the and this could also cause a sluggish start condition
