when i leave the vehicle parked for short periods from 1 or 2 hours my ignition fails and turning over many times to start it. when cold or left for a up to 10 mins the car starts no problem. i have had the ignition cleaned and throttle body checked over but still seem to have this problem. serviced 2 months ago. This is a recently bought vehicle and i cant get access to knowing about the previous history.
cannot think of what else it could be? its at 240k but as i said cleaned and checked and serviced a few months ago

 

What is your year and model?
