Could be the coolant temperature sensor or stuck thermostat - reasoning is as follows.
Cold Start - mixture is enriched - no problem.
Hot start - mixture enriched due to coolant temp sensor telling DME that the engine is cold so the beast won't start until you push the gas pedal down, which allows more air into the engine - so it starts. Erratic idle due to overly enriched mixture (engine hunting.)

When it dose starts up, is it a rough start??
If it is It could be your fuel injectors, my dads 91 mercedes dose kind of the same thing but it starts up.. when its cold car stars fine drive it to the store, come back car starts really rough or from second time because his seals on the injectors are worn and it leaks gas. Also maybe your mass air flow sensor is going out? it cant tell ecu how much air needs to go in, so it prolly takes too much or not anough air. That causes the problem sterting.. Starter? i had similar symptoms to yours when my starter started fuking up. My car would start up perfectly in the morning then i would park it and come out later and would take me a couple times to get it to start. These are my guesses

The car will only overheat if the thermostat is stuck closed - if it is stuck open it will take longer to reach operating temperature, resulting in slower warm up, rich mixture and poorer running until the engine gets warm. Since a relatively small vacuum leak can cause similar problems, the next step is to pull the codes from the engine....

of us to understand what you are saying.

to say.

A bad earth/ground can be very hard to find. If you know where any electrical or body work has been done to the car, those are the places to look first.
