There is a ground where i'm sendign the pic, behind right pillar that may be loose. Also make sure that eh blower is getting power just while standing still. If it'snot check the relay it may be bad.

The next time it happens, grab a large screwdriver by the blade and rap on the blower motor with the handle. Most of the time it's just a worn out motor and jarring the brushes jump starts it.

You might have a failing blower fan motor. Give the blower motor housing some banging with your hands and if the motor turns on, it is due for replacement.
