1999 996 won't start when hot (cranks)

A few days ago my car started not starting when hot. It seems somewhat random when it will happen. I think it is heat related because it starts fine after sitting and today it was much hotter outside and I had to wait over an hour before it would start.

From reading the forums I thought it sounded like the fuel pump. I put a gauge on it when it wouldn't start last Friday and jumpered the fuel pump relay and it was only making 15 psi. I ordered a new fuel pump and installed it yesterday. Put the 5 gallons of gas back in and drove to station and filled tank full last night and everything seemed fine.

Today the problem was back. I put the pressure gauge on and there was no pressure. Cranked the engine and no pressure. Jumpered the relay and went up to about 60 psi. Cranked engine and still no start. Let cool for an hour or so and started.

Now I am at a loss where to look. This is the first problem that I have had with this car so not real familiar with what to look for.

Thanks in advance for any help.
