When I apply power to my breadboarded ATmega 328 with a small DC motor driven through a logic level mosfet, the voltage measures about 5v then drops to around 2v after 4 or 5 seconds. EDIT: I'm referring to the voltage between the output pin and mosfet gate. The rest of the circuit measures 5v where…

Mosfet gate voltage

How you power the motor? It is a 3V motor.
