I tried my first tank of WMO blend today and engine shut down after three blocks. I filtered the WMO through 1 micron filter and water separator. Good looking batch of lube oil that came out of a CAT engine I manage. I mixed 20 gallons of WMO with 30 gallons of straight diesel. Engine has been running good with no problems on diesel. The WMO has lived in a 50 degree F. garage as has the deuce. The weather outside was about 33 degrees F. so should not have been a problem, right? Not too cold for a 40% WMO to 60% diesel mix. It was not even outside long enough to get cold. The engine just slowed down and stopped. It would crank but not fire. I got it towed back to the garage and after 4 hours in 50 degrees F. it would still not fire. I checked and had good fuel supply (black but thin) at the top bleeder on the secondary fuel filters. I changed the primary and secondary fuel filters anyhow. Still no fire. Anyone have any ideas?

I always add some regular gas just to thin it out...it's possible that you have an air leak or blockage in the line that coincided with your first tank of alt fuel.

What you have described sounds like filters to me. Sounds like they were questionably close to being plugged and the thicker fuel put them over the edge. One other thing, is the in tank pump operating? Since I don't know your truck, I have to ask.
One of the SS members tried some warm WMO in his truck for his first alternative fuel batch and he made it about 5 miles before breakdown. Turns out the warm (HOT!) WMO caused the rubber hose inside the tank to pop off the fuel pump outlet bung at the top of the tank. His fuel pump was working, but the WMO/Diesel mix wasn't making it out of the tank. Another SS member let him borrow an external fuel pump until the internal rubber line was replaced. Although the warm WMO caused the rubber hose to swell and pop off the outlet bung the hose had definitely reached the end of its life (split, cracked and rotting).
Thanks for the ideas! I suspect Gimpyrobb is right. I was waiting on changing the fuel filters till I had run some WMO mix through them. Today was my last day at home before going back to my ship, so I just flat ran out of time to troubleshoot. I did check that I had fuel at the top of the secondary filters, did not have time to try alternate fuel sources or even bleed at the injectors. The fuel had flowed that far in the system and was black, but fairly thin. That tells me that at least some of my fuel mix had made it through the filters. Perhaps, just not enough flow to sustain engine RPM. I did not heat the WMO, It was just ambient temp of the garage, as was the diesel fuel in the tank, prior to introducing the WMO. Now I get to spend two weeks on the ship and worry about it, before I can work the problem. I got the filters changed, but did not have time to bleed the canisters and retry a start. When I get home I will do that. If that does not fire, I will try to setup diesel in a boat tank with external pump and purge the lines to the injectors. I will post the results of my efforts. Happy New Year to all

In this case it was all Chevron Delo 400, which is not synthetic, but it is something to remember for the future. I will get back to working on the truck on tuesday.
