I didn't take time to look up your model, but I have encountered a few Gravely's with the problem you experiencing---particularly if the fuel lines exit the top of the tank(s). Check the drop lines inside the tanks--they start to crack as they bend off the elbow in the tank allowing the fuel pump to pull air. For a time, Gravely was using an inferior drop line. Keep in mind that there is a weighted fuel screen on the end of the line--in both tanks of course. The problem fooled me once--not again.

If this happens to be the case, replace with 1/4"ID Tygon.

Ditto Dutch...
Had one of those drop the weighted screen and it ran when it wanted too...
Replacing that line can be a challenge...

Could be.the solenoid..
Did you replace the short hose. From the fuelpump to the head.???
If it leaks..the fuelpump can be intermittent...
I would put a bent coathanger in the tank and fish out the fuel line to make sure the weighted fuel screen didn't fall off...

Yes I have replaced the short Vac . line and checked the lines inside the tank.
I'm thinking the solenoid is all that is left, and those things coast about $135.00

Remove the fuel solenoid and check it. Sediment can collect around the plunger of the solenoid making it sluggish/inoperable but most of the time they can be rehabilitated.
