Engine lights, anti theft lights flashing at the same time, car stops

Hello. I was driving yesterday, and suddenly, after 4 minutes of driving the engine lights and the anti-theft lights started flashing at the same time, the car started to shake, and at the same time the revolutions per miler were acting like crazy, like going up and down and after that, the car just stopped. it happened a couple of times.
Someone from here had the same experience? I want to buy a diagnosis scan, but as I have a March 2001 Jimny I don't know if will work?
Thanks for your help

It sounds like a broken or failing earth wire or bond, my reasoning at this time is too many things happening all at the same time, so you need a common failure. First step is to source some circuit diagrams and check the earth wires. Second step is ask the ECU what's up (if you can), random problems also backs up earth issues.
I can't help on Circuit diagrams or if the early Jimny can be scanned, but someone can I am sure.
Early days and just an educated guess at this stage, but you need to start somewhere.

Hi! Yes a diagnose should work. However it sounds a bit like when my dash cluster was broken. The coms between the Immobilizer (theft light on dash) and the ECU and cluster was damaged from an idiot disconnecting the china made obd2 interface while the engine was running.
Could also be a sensor failing.
But first like Scimike said.

Thank you!! I’m trying to understand everything ❤️ I will read it properly later. English is not my first language and honestly I’m a bit( a lot) lost with mechanical words. Do you think I will be able to do it by my own? Thank youuu

Do you think it can be as well the battery or the crank or cam sensor? Just sooo confused. Never happened to me. And my garage is so far away from my house. I will try to read a scan today. But honestly not sure if will work on my car. Let’s pray

I think at the moment it could be anything.
RE battery you can check it if you have a multimeter, should be more than 12.4 engine off (no lights), 14v with engine running.
Hope the scan works.
If you have any more information just post it, everyone will try and help if they have a suggestion.
Good luckM
