Prius 2004 230k miles

I use my Prius for deliveries, I drive about 6 hours and 90 miles a day.

When I start in the morning, it is working perfectly and continues like this until I complete two and a half hours of work, it has been like this for two weeks.

When I complete about two hours of work, the red triangle and the exclamation point appear on the dashboard, but the car continues to drive normally.

After about four and a half hours, the combustion engine does not turn off when the car is stopped and the car starts to lose power when it comes to moving. Fuel consumption, which was high, starts to drop below 30mpg and the car seems to be making more effort to drive.

The next day in the morning, I reset the error and the car runs normally, until all this happens again.

I replaced the inverter pump and control valve, I also replaced the electric battery fan.

There is no check engine, there is no code just the red triangle and the exclamation point.

Fuel consumption is very good, 45-50 mpg but after four hours the hybrid won't run anymore.

The problem is the hybrid battery? because it works normal for both of them until the problem occurs after hours of operation.

found out the problem, there is a blue rele near the fan and it was damaged, after changing it, everything went back to normal.
