Well there are a few possibilities. Without getting too crazy with ideas you should do some basic tests when the vehicle takes a long period of time to crank.
Measure your fuel pressure at the rail, it should be around 36-38psi.
Check for good bright strong spark when the vehicle is cold.
If it passes both of these tests reply back and I will further guide you into what it may be.
