When you re-fire it are you filling up the fuel tank prior? we had a similar issue this past weekend, what had happened was inside the fuel tank where the rock filter connects to the tank had a small leak. As we ran the car and the fuel level got right to the connection of the tank and rock filter it began sucking air and fuel. This wont show up if you pressure test the fuel tank under water. The easiest way to check if it is a fuel leak is look at the fuel line, make sure you have a portion of fuel tubing that is clear, and run the car until it dies, then look at the fuel line, there should be no air bubbles. Try re-firing the car and see if it continues to have air in the line, if you have air then you can narrow it down to a fuel delivery problem and not an engine problem.

Update!!!!!
Here is what I did.
Front Diff. Bearings good gears good filled with new oil.
Center Diff. Bearings good gears good filled with new oil.
Rear Diff. Bearings good gears good filled with new oil.
I took apart the entire clutch. Shoes were good, springs were good, all bearings were good. The front engine bearing was good as well. I did notice some wear on the clutch bell.
Pulled the gas tank off and did a leak test under water. No leaks.
I put everthing back together cleaned every part and made sure everything was in working order.
As usual started right up and the idle was perfect. Put it on the ground good punch on the low and at high speed performed perfect. 4 minutes into it once the temps were at the appropriate tempatures it flammed out.
Pulled into the garage and put it on the box and it restarted no problem.
Leaned the low end 1 hour. After 5 or 6 minutes flammed out again. Pulled it in again and it restarted no problem. Leaned another hour on the lsn and had to stop.
I have nearly torn apart the entire buggy and everything seems to be working perfect. Power band was awesome and it ran flawlessly until it hits the 5 minute mark.
I am clueless now!!!!!!!!!
