Really thinking it's an issue with the motor. I'll call the manufacturer tomorrow, hopefully they get a new one pretty quick, because at 110 degrees, I'm have a really green pool in just a few days.

Just curious if you normally run it during the day, every day? Most folks here run their pumps at night (8-10 hours for the "average" size pool/pump).
That way the motor isn't baking in the sun
while running, and it saves you money (off-peak hours).
Only other things that come to mind besides blocked air vents and/or bad running capacitor would be bad shaft seal and/or bearings, suction or pressure side restrictions, or any previous "thermal events" that could have melted the coating on the motor windings causing a short. If it's the latter, it will only get worse until it finally won't even turn on at all. That typically happens when the pump is ran dry, or without sufficient water flow (and it only take one occurrence to start the downward spiral). Is the trap filter reservoir completely full and free of air bubbles when running?
Regarding the cooling vents, some pumps have little "ducts" inside the motor cover than can get clogged. So, just clearing debris away from the openings may not completely "unclog" the airway.
Also, if it's not running optimally or long enough each day now (and it could be a few days to get it repaired/replaced) you may want to shock the pool ASAP.
