Thanks again for all the advice. 
I just purchased the vehicle a little bit ago and was told not to drive because the engine was blown it smoked in the Grapevine then it stall when hot and will not restart until it is cold again.

So I did a compression check on the cylinders and all within spec (Cyl 1 115psi, Cyl 2 80psi, Cyl 3 110psi, Cyl 4 75psi), I figured to do this before pulling the engine, good thing! 

So I decided to drive it and put some gas in it and drive back home until it died and I could not start it again. Then I noticed fuel leaking from the tank. So maybe this leads me to think it is a fuel problem, besides the safety factor, could a not sealed tank cause the engine to not run right?
