Car starts, runs fine for days, when I hit a big bump engine dies, idiot lights come on for 2 seconds engine catches and everything is normal again.
My guess is a intermittent / loose electrical connection? Where should I look?
I love this X300, but it has more relays and connectors then an F4 Phantom!

Thanks

 

There is an inertia / crash switch on the cars right side fwd of the right front door hinge on the cabin fwd wall that can be intermittent when hitting a bump

This will drop out your fuel pump among other things

To override the switch you can put a paper clip in the switch connector between the 2 white wires

Those Phantoms were laud taking off for yonder ways
