It does not like to start once it is at running temperature, starts but, seems to need fuel. When it is cold it fires right up. I changed the fuel filter but the problem is still there. When running it runs great, checked with an obd reader no codes come up. Help

Good afternoon.

I would start by checking the actual fuel pressure. You need to check it when the engine will not start. It sounds like a failed fuel pump.
