You have either:
– Wiring issues (not enough juice flowing on the wires going the sensors mentioned in the tester thing you have) , new harness or remove it complete and clean every part of it with contact cleaner – do the same for the sensors connected to it.
You should have less errors. The ECU is annoyed hence it will keep cutting off
And make sure even the battery is properly charged & the regulator is doing “Minimum” 14v to it (no less) (even if it’s idling)
Fuse boxes may be rusty too. Including relays.
Or
the parts themselves mentioned have issues / faulty (temperamental behavior). Ie, faulty coil means it works then it dies.
Or
ECU itself has gone faulty , I hope it doesn’t come to that!
