206 1.4 LPG instant stop engine light not starting

1. The problem is that my vehicle has a sequential system, Atiker LPG, and at the first start, it shakes at idle, when I switch to gas, it gets better when I use the vehicle for 1 day without gas, this problem disappears and goes down to minimum levels, so sometimes it does not do it for a very short time, in a way that is not obvious

2. The problem is an important issue, the vehicle suddenly stops while driving on the road, regardless of speed and rpm, and the starter does not start at all, when the battery terminal is disconnected, waited for 10 seconds, then the only starter works. This problem started this year

3. The problem is when the vehicle is on the road, it suddenly cuts off the ignition, it works instantaneously, this event happens in 1 second and the engine light comes on after 3-5 seconds, there is nothing in its traction, it continues on the road as if nothing happened

4. The problem is something that happened to me 5-6 times, sometimes the car gives gas by itself, sometimes the engine light comes on when I start it for the first time. Once I was driving with 70 80 on the road, the engine started to wobble and vibrate. It goes between 2.5 and 4 thousand cycles. The 4th problem is solved by removing and plugging the terminal, so there is no problem when I remove the terminal and it continues as if it never happened

I set the car clock at night, I set it again in the morning the clock is always changing, you will say because you unplugged the terminal, but I do the editing after disassembling and plugging it in. I put the tool in, all filters, engine oil, timing set, circulation, alternator, belt and bearing, spark plug, antifreeze, all changed, but the problem still persists

Thanks in advance best regards..
