I don't think the air gap would disengage the clutch. Keep it from engaging, yes, but once it's engaged it should stay engaged until the magnet is de-energized.
Somehow the magnet coil is loosing it's power source, or there is an internal short/open in the coil.
Being it immediately reconnects when the switch is cycled, I would suspect the switch is failing. To verify it is the switch, you could bypass the connection with a jumper wire. But, be sure you are on the correct terminals! There are several terminals on the switch. Jumping the wrong ones could be a costly mistake.
There are other safety switches that control the clutch. Finding an intermittent problem can be difficult, a matter of catching it in the act. A wiring diagram would be helpful to see what all is in the clutch circuit.
Just the nature of the beast makes the wiring to the clutch subject to vibration and damage. Most have a plug near the clutch harness, might check that connection, and the harness in the area of the clutch.
If there was a previous problem with the charging system, as in the battery discharging while running, the clutch could have been damaged. If the voltage dropped to the point the clutch was slipping, it would have overheated and could have damaged the insulation in the magnet coil or the incoming wire harness. Look for heat discoloration on any clutch related components.

Today's Featured Article - The Fordson F Ignition System - by Anthony West. A fellow restorer contacted me earlier this year asking for some help and advice on a model F that he was restoring. He had over a period of months spent a fair amount of his hard earned cash on replacement parts for the old "trembler" ignition. Sadly though all his efforts seemed to be a waste of time and money as he still couldn''t get the temperamental old thing to run correctly!! If i said that this was a little frustrating for him that would be "conservative" in fact the problem had reduce
