In Minnesota if an employee does not report to work and does not communicate a reason why for three days in a row, they are assumed to have resigned (quit) their position. The employer only needs to show that they made a reasonable attempt to contact you and determine why you weren't coming to work. They then just send a notice that you are no longer employed by the company.
"Fired" can mean "terminated for cause", "terminated for performance", or "terminated" which all have different legal meanings.
If you are asking if you qualify for unemployment money, that will be determined by the unemployment office. There is not way any of us on this site could know what the outcome of that decision will be. The unemployment agency will decide that based on the details of your situation and your former employer's input.
