That sounds a lot like there is a bad connection somewhere. The additional current draw from the headlights may be causing the voltage to drop too low to keep the fuel solenoid on.

Unplug both head lights and see if you still have the problem. If yes, problem is in switch or wiring. Maybe wire rubbed bare and causing partial short? Bad switch? If it is like mine, round with lever on side for flashers, it is pretty easy to take apart and clean up contacts, check for broken parts.
If no problem, plug headlights in one at time. If problem comes back with only on or the other light plugged in, problem is with that bulb or wiring to it. If problem comes back with either or both plugged in, you are back to chasing the switch or wiring.
Any snow/ice packed in behind the dash or around the headlights? Good luck, surprised it didn't just blow a fuse.

I took your advice and unplugged each headlight bulb one at a time and no change. I took apart the dash and removed the switch. The back of the switch was really dirty so I cleaned it with electrical cleaner and blew it off with the compressor. I re-installed the switch and sometimes it would kill the engine when turning the lights on other times it would not, so it looks like a new switch is in my future.

A new switch may work but you may have something like suggested above. Your tractor may be of the age that you have a lot of corroded connections. Even with a voltmeter you might have a hard time tracking this down. If switch doesn't fix, I think you will need to open all connections you can find and clean. This includes all connectors, both ends of battery cables, all grounds. If you can't isolate the problem, which is very difficult with these multi-contact connectors, these electrical gremlins can be hard to fix.

I replaced the headlight switch with a new one ($65 ridiculous) and every once in while (intermittent) when I turn the lights on I get a split second sputter but it stays running. It seems that when you turn the lights on it's taking juice away from something else. I hate these electrical gremlins.
