Pressure washer shutting off after 10-15 minutes

Ok, I've been at it all day. Let me tell you what it's doing and what I've tried. The washer starts fine, pressure is fine but about 10 minutes in it shuts off. I will restart it then it works for 5 minutes then 2 then 1...ect.

The pressure washer is a generac 207 bar 3000psi and does have a low oil turn off switch.

I have done the following:

New gas in tank
Flow from tank
Oil change
Cleaned air filter
New spark plug
Loose gas cap for airflow
Checked lines to carb from tank
Cleaned carb

The only thing I can think of is it overheating then shutting off OR the low pressure oil switch could be malfunctioning. Has anyone had a similar problem or know what I should do? I can't find the switch to save my life but I know its on there somewhere.

Thank you.

Does it ever shut down for good and not restart? If so, check for spark when it won't run. If not, it sounds much like a fuel problem, like the flow into the bowl is insufficient.

Try disconnecting the wire to the oil pressure switch. I had the same problem and if I disconnected that wire. It ran perfectly. I changed my oil filter and was able to reconnect the pressure switch.
