Will start cold but idles rough and cuts out. Won’t go until it warms up for 3-4 minutes. Then runs fine. Until you shut it off won’t restart for an hour or so and does something again. Checked fuel filter and fuel pump seems to have plenty of fuel pressure.

Have 2 620i gators. It's an ongoing battle, always working on them. The tech manuals are really good, I would get one. Relays, sensors, and main harness seems to be most of the issues. Not made for farm work.
