873 STARTS THEN DIES

[TW873]

I have an 2000 873. I changed the hydraulic filter under the cab, and the it started this. It started then it dropped rpms and almost died. I changed the fuel filter and bleed the air out. Then it got worse, it dies now. Starts right up like it should when i turn it over a second time. I get no codes when i hold the light button down. Dealer told me to swap some relays under seat, i did that, no change. Thanks all.

Almost sounds like the hold coil on the fuel shut off solenoid is not holding. It will pull in to crank, but when that coil is de-energiszed, the hold coil doesn't hold it in place and the engine shuts off.
Could it be as simple as a bad solenoid?
You should have 3 wires, ground, pull and hold. Hold should have power when the key is on, pull should only have power when cranking.
