Let me preface this statement with the disclaimer that if it doesn't start when we turn the key I call the dealer and let them fix it
It may not be your equipment, it may be your source of fuel. We fuel our vehicles (all deisel) at the same place. This sounds like common sense, but the source for your fuel needs to have high turnover to provide consistent fuel quality.....important up here in the middle of nowhere.
Maybe your source for fuel has a water leak in their tank and you are getting contaminated fuel to begin with.
Consider this an intervention

and don't jump off the bridge.....try another fuel source.
