Fan kept running when auto turned off and when i killed the power and turned it back on the blue wire spat sparks
Bad connection. Shut off the power and re-crimp the connector or replace it. Take a picture of the connector and go to the hardware store and ask a sales associate for the connector.

Remove green (fan run) wire from thermostat, and connect to red wire (power) and see if fan runs, and if it will stay running. That will by-pass thermostat to see if it is problem. If it continues to run, thermostat is problem. If that doesn't cure it, I'd remove cover up top and with power off at circuit breaker, blow compressed air in to motor air holes to make sure it's getting proper air for cooling, as well look for small plastic plug on housing where oil can be added ( few drops) to lubricate motor. Leave cover off and try fan to see if that may help. If at all possible, a clamp on amp meter will confirm if motor or relay is at fault if none of these suggestions help. If amp draw at motor too much, motor may be seizing when warmed up from running. test draw when first started and after running for amount of time that it usually quits, and if noticeable difference, motor is seizing and needs replace. You can also test amp draw at main 120v feed wiring with unit just in fan mode.

Testimonial: "Thank you very much Mike for the answer. It WAS the thermostat. I completely ruled it out since it was just replaced 2 months ago. Thanks again."
