One of the techniques for finding problems is to disturb the cables. This checks for poor connections . Given you documented this above , it becomes likely that there is a bad connection either in the positive or negative wiring . It is also possible that this is temperature related.
in older times, I had a car that would start and fail when driven a few feet. Wait 5 minutes and it started again. Fault was a loose connection which broke with the vibration and settled back when stationary.
let’s hope it’s a bad connection and it fixes very easily. Tampering with the wires is a recognised technical method
