On 2nd pass bit plunges and easel stops

I’m very new to the process. Any help appreciated. When I do a simple project as my name using 1/8 downcut end mill on a scrap mdf @ .250 thick I’m asking easel , cut the depth to .125, and each pass 0.0625. Easel cuts 1 pass, plunges the bit for second pass, then the project stops, spindle stops and project says 35 % done. Will not move anymore.
Help all you wizards, please. Thanks, Tim
