Check to make sure that your agitator still spins. (Agitator = brush). If your agitator still spins, it eliminates your belt and agitator as likely culprits. The last possible solution would be that your vacuum is clogged. The grinding sound might be a motor-related issue or could possibly mean your bearings are going out. Check the bearings of the agitator and the motor of the vacuum.
Accessing to the agitator and belt can be done by removing the bottom cover of your vacuum. There are 2 scews that are holding the bottom cover to the head of the unit. Remove these 2 scews and the bottom cover should snap off.

Greetings from GoVacuum.com,
It sounds like you may have a bad thermal switch inside the machine. Most vacuum cleaners have a switch connected to the motor, so if the vacuum cleaner is running hot, it will shut off to prevent any damage to your motor. You did all the right things by checking the bag, making sure the hose was NOT clogged, and replacing HEPA filter.
Most of the time on canister vacuums, the reason is caused by a clog in the hose, or somewhere in the powerhead. If you're sure that there is no clog anywhere, it is going to be the thermal switch on the motor.
Here's a link to the parts schematic for the Bosch upright vacuum. I hope it helps you in determining how to access the thermal switch. A word of warning to you before you try it, this is a very tough vacuum cleaner to work on, you may want to bring it in to a vacuum repair shop, as this is not an easy repair.
Here's the link;
Please let me know if you have any other questions,

SOURCE: suction problem
check the intake hose at the bottom it may be clogged.try blowing into the long hose if you can't blow through it then you have a clog somewhere between the long hose and your intake hose at the bottom.the intake hose is the somewhat clear hose that comes up from behind the base at the bottom.you will see it on the backside

Theres a little bendable neck that hose with suction plugs into. Thats the one thats clogged. You will have to fish it out by taking off the roller and clearing the clog.
