My Genie Z45 manlift runs on propane but recently I've been having a problem with it stalling after it warms up a little. Let it sit for a while [30min] and she'll fire back up and run fine until it warms up again. I don't see any choke adjustment or fuel knob I can experiment with but before I call out a lift mechanic I figured I'd ask this forum if this is a familiar problem with an easy fix. {Well, I can dream}. I'm also going to try another fuel suppler but I saw no problem the last couple of months on the current fuel -of course, it was warmer.
Sounds like maybe the propane system is freezing up. Is there good coolant flow through the converter?
Check coolant level, those evaporators gets ufreezed with hot coolant. Maybe someone pulled thermostat out of it.
The evaporator could be gummed up with wax inside
