I'm not sure if the inertial switch can be reset just by towing the vehicle.
Also, it takes a pretty big hit to make it kick 'OFF'.
It might be the fuel pump itself is getting stuck....really!
My Marauder would sit sometimes for so long that when I keyed it 'ON' to crank the engine the fuel pump would not run and pump.
I couldn't hear it humming/priming before cranking the engine over.
A simple bump on the fuel tank with a rubber mallet with the key 'ON' ..... and I could hear the pump crank up and start humming again.
Then my Marauder would start like a charm.
This happened to me multiple times.
