Took the truck to MA this weekend hauling a small utility trailer. All highway. Stopped on the way home after about 130 miles of driving at a rest stop. Let her cool down (egt's to around 300 degrees) for a bit then shut down and went inside to eat. Spent about 20 or so minutes, came back out, hopped in, hit the key, WTS light shuts off, crank, fire, die. Huh.... Key on, crank again crank crank crank crank fire, start run. No problem.
Got home, backed into the driveway,cool down, shut down. Come out half an hour later, crank fire stall. Crank crank fire start run. No problem.

Odd behavior????

 

Mine does that exact thing when the fuel filter needs to be replaced.

 

Hmmmm... Fuel filter was replaced within the last couple thousand miles... Could be gunked up tho....

 

Well it may be something esle maybe LP or Ip. I just know that when mine gets bad you crank it and no more than it starts it dies, then crank it again fires right up no problem, but i lose alot of my smoke.

 

Check for air in the fuel... You could have a air leak in the system causing the hard starting.

 

Haven't run it today. It's home in the driveway. Will check starting when I get home.

 

Truck has not failed to start since. Am replacing the LP soon tho.
