Hard started when warm

I had a similar problem on my 87 5KTQ. Fuel pump check valve was the
culprit. It is on the top of the fuel pump. It was leaky and didn't hold
fuel system pressure while the engine was warm. When it cooled down, the
cold start valve kicked in. I used to start the car by activating the
cold start valve manually with the output diagnostics (via cockpit
installed button). It was a pain, but it worked (until I replaced the
fuel pump w/ check valve).
