My 3sge toyota problem is when the engines is running then after 3mins the engine will stop then it is not starting again,but when the engine is cold it will strart again.

1. Cold weather: Cold temperatures can affect the performance of the engine and make it harder to start.
2. Battery issue: A weak or failing battery can cause the engine to take longer to start.
3. Starter issue: If the starter is worn or damaged, it may struggle to crank the engine, especially in cold weather.
4. Ignition system problem: If there's an issue with the ignition system, such as a faulty spark plug or ignition coil, it can cause the engine to crank for a long time before starting.
5. Viper DS4+ installation issue: The Viper DS4+ remote start system may not have been installed correctly, or it may have a defect that's causing the issue.

I have same problem however, at time, I cannot accerlerate unless I switch off engine and restart again. This mostly happens after my RAV4 has cold engine ( cold in Africa standard ) Been told by CFAO socaoled Toyota dealer but said that injectors must be removed etc. etc..
What is the best thing do ? Is it safe to be driving with this error code?
