Perhaps they meant radio frequency interference (RFI). Conceivably the electric motor in the head is generating a signal that is getting into the propane switch and causing it to flip off. This is less likely if the motor has a metal case; if it is metal try grounding the case.
You might also try shielding the propane switch. Before you put a lot of effort into a nice permanent shield, pull the switch off the bulkhead and put it inside a grounded metal box (you can bend something up from any kind of metal mesh).
