Honda powered Pressure Washer Problems times two

[tackleberry]

i have two pressure washers with GCV-160 engines. They both pump fine, when the engines running. They both start up easily,run for a while then just shut off. I've drain tanks and checked for fuel flow. I have checked the caps to ensure the gas cap vents are clear. The carburators have been gone through and i believe they are working properly. Once they die, they usually start right back up.
Stumped!!

Verify strong blue spark when they die on you. Those crappy inline Christmas lights can help you. Coils need to be load tested as well.

Pull the kill wire off the coil. Should drain the fuel tank before they die.
