Describe your issue:
Ive just fitted a new spider hot end to the printer and when i power it up it right away throws up the error message above. Ive tried disconnecting the new lead to the hot end but it still persists. Any ideas?

Unfortunately, it looks like your micro-controller is spontaneously resetting itself.
The Klipper host code had an error that caused the spontaneous restart report to not propagate correctly. This should, hopefully, be fixed now (commit 9ce631e8).
As to why the micro-controller is resetting itself - I’d try investigating the possibilities described at Timeout with MCU / Lost communication with MCU . You may also want to try running “make menuconfig”, compiling, and reflashing the micro-controller again.

Its not been fiex yet, im reflashing it tonight having checked my wires with a multi meter and found no shorts.
As stated by @koconnor: Your issue is most likely related to some hardware instability. Provide a new log after updating to latest Klipper and see:
What has been fixed is that the actual error is not “correctly recorded”
