XJ won't start after warmed up! Need you help

[Built2kill]

IT NEVER ENDS WITH THIS TRUCK! I replaced my ignition coil because she wouldn't even start up. Right when I replaced it it fired up so I let it warm up to see if I still had the existing problem. It would shut off and I hear the fuel pump automatically restart back up if I crank it it would fire right back up for a few minutes then repeat the same problem. No codes as of yet. I'm stumped once again. Any suggestions of what to check now?

Check for an exhaust manifold leak blowing on the CPS.

Also, get out an ohm meter and start testing the CTS, and MAT sensors when hot.
