Install a new fuel filter and fresh gas?
At least make sure your getting gas to the throttle body if you have spark.

guys, i just went out after cooling it down and it ran just fine. left it running for like 45 minutes. i did unplug the neg side of the battery earlier but still died. just thought i could reset the computer. now its running fine. i will drive to work in the morning and repost what happened. but please keep them coming. the guys that posted, thank you, i did check all of that but didnt post it. thank you and keep up the help. one thing i can say when i started using usmb long ago was the boys.....always keep me on the right track to diagnosing my problems. thanks again to those who have posted.

Dying coil. Tach dropping to zero before engine dies is a strong sign.

Maybe it's your Enkie wheels? Maybe the RX doesnt like them and you should give them to me.
