1997 GTX Quits when it gets warm.

[Perchecutioner]

Just overhauled entire fuel system. Cleaned gas tank. All new lines. New petcock. New filter. Both carbs rebuilt. It runs great when its cold but after awhile when it gets warm it quits. No sputtering just quits altogether. It can be at idle or up higher in the throttle. If you are cruising at two thirds throttle after she gets warm rpm’s may drop just a hair. But when it quits it’s like you hit the kill switch. Any suggestions? Thanks in advance.

I did wiggle the lanyard around and pull it off at an angle etc.. but machine did not quit. Do I need to take it apart and check wiring or something?
