JD 200 D

I have a JD 200 D that came to the shop last week. After getting it hot and running it hard, it will loose power and cut off quickly. It starts right back up. The filter housing assemblies were both replaced by the customer, prior to bringing it in. I see no sign of fuel leaks or bad lines. It acts like it is running out of fuel. Any ideas or experience with this symptoms.Thanks for the help.
