Dci cutting out over bumps

[Archtronics]

I’ve been trying to repair the daily derv while we are stuck in lockdown and it’s got the weirdest fault.
It wouldn’t start initially so replaced the crankshaft sensor and now it will run.
but if you drive it over a bump or even close the bonnet with it running it cuts out.

I’ve wiggled every wire I can find, but nothing it’s really pissing me off now, not flagging anything up on the computer either.

Any ideas?

Engine bay fuse box would be my first port of call, pull the relays out, clean up with a bit of sandpaper and re insert. Also make sure battery terminals are secure
