I was getting ready to g to work tonight and my 07 RK sat @ idle for about 5 minutes and died....I will turn over but will not start...where would I begin to trouble shoot this?

 

Divide and conquer, 1st check to make sure it has fuel, then spark.
Pull the plug wires from the plugs, turn over 3-4 times, then pull the plugs and see if they are "wet" being containing fuel. If not, start back tracking.
See where the fuel stream stops.
If you have fuel, get a hand held tach (or meter with inductive pickup) and see if you have spark out near the plug boots, with the wires attached to the plugs.
If no spark again start back tracking.
A service manual is priceless for prints, and specs. Make certain to have one.

Could be as simple as a broken fuel line in the tank, or a switch which feels fine but the contacts are toast in.
