Hello,
Unfortunately we are not qualified to be able to diagnose the fault you are experiencing.
However, a common issue with electric blower vacs losing power is typically the result of a blocked air filter. Air needs to be able to move in and out of the motor and it usually passes through a filter.
However, the filter can become clogged by dust and dirt which can reduce and even stop the air flow from being able to pass though. This can result in the blower not starting, having poor blowing/suction power and losing power.
The filter should be regularly checked and cleaned to prevent it becoming blocked.
Thanks for using Q&A.
