Hello, so I have a Seat Toledo mk2 2001 petrol engine 1.6 16v (code name AUS) converted to LPG with Lovato's kit SmartExR and I came across this problem while having a big trip for about 3 hours using only LPG. The car was driving fine around 130-140 km/h until we tried to make a stop. I was in 5th gear with around 3k rpms and I put it in neutral then the car suddenly died while running instead of staying in idle. I pulled over quickly and tried to turn it back on and it did yet it died once again after some seconds. After that nothing I tried turning it back on but no luck. My insurance came and took the car with a trailer. About 1-2 hours after they called me and told me that the car started up with no problem so the next day I picked it up and made a 2-hour long trip with only petrol and everything was fine. Any idea what might cause that issue?

Crank position sensor or fuel pump/ pump relay would be my best guess, but could be other things. Any fault codes stored?

Nope, nothing we even checked the lpg system and everything seems to be fine. Since that day the car is running normally. It has a problem with rough idle but it doesn't die when it's on idle, only the rpms are not that stable.Idk if those 2 are related.
