Hoover stick vac turns off

[abunaitoo]

I have a Hoover BH52230 bagless stick vac.
After about a minute it turns off.
Lights on the battery life are still on.
I turn it off, and it starts again, but last only a minute.
Even with the filters and wand removed, it does the samething.
Battery lights show fully charged.
Just started happening.
Any suggestions???
