Went hunting around noonish and hitting the offroads pretty hard and mud holes having a good time thrashing on the ole gas hog, this is way after the mud part , but i hit some pretty good dips in the road, pretty fast and hard, when i hit the biggest dip (wheels didnt actually come off ground but sure felt like it) the truck just shut off , died , nothing , no power, stopped,. cranked it over like nothing happened and went on my way back thru the mud holes down the mountain and hopped on the 70 mph freeway to home, temp, oil pressure, trans shifting as usual , had a half tank fuel thinking it was some safety feature? been up this road more than a few times , first time i ever had anything like this happen. battery cables, alt cables all tight and sucure

 

I'd guess that you probably jarred the ASD relay or some loose electrical connection somewhere.

 

wouldnt worry about it, that much vibration is bound to momentarily to disturb any number of connections
