BE40 flight crew experiences a dual engine failure at FL430 after starting a descent due to stick shaker activation while deviating around thunderstorms. The engines are unresponsive resulting in a flaps up dead stick landing at the nearest suitable airport.

Narrative:
Cleared as filed; climb to FL230. Step climb as instructed by ATC to FL400. At FL400 we were on top until thunderstorm cells approximately 100 NM ahead showed on radar. Climbed to FL430 to stay on top of cloud layer. Deviated 20 degrees right to avoid thunderstorm cell in flight path. Climbed to FL450 to stay on top as we deviated west around back side of thunderstorm cell. ATC advised another aircraft topped the weather at FL450. At FL450 we were on top and past the thunderstorm cell with another thunderstorm cell approximately 50 NM to the southwest of our position. We started the turn back on course behind the thunderstorm cell and approximately 50 NM in front of the other thunderstorm cell. ATC advised an MD80 experienced a 30 KT drop in airspeed at FL370. We were at FL450 starting to go in and out of the tops of the clouds (-40 degrees C) when the stick shaker activated. We advised ATC we could not maintain FL450 and requested lower. Engine heats were turned on as we were descending from FL450 through FL430. I heard a thud and we entered intense rain. Before reaching FL400 both engines flamed out. I asked the first officer to change seats with a company captain (riding in the cabin). We performed the checklist for an air start. It appeared we did not have rotation on the engines. We tried a starter assisted start to no avail. Requested vectors to nearest airport. Broke out of clouds at approximately 8;000-6;000 MSL and landed.
