esko mk1

I own a small turbo escort cosworth with a problem.The problem is that when I start the engine cold it starts ok.Let it idle to the normal temperature about 15minutes and it just cuts out.Just like if you turned off the ignition.If I try to start again,it wount start.Engine cranks properly when starting.Let it "cool" about 5 to 10 minutes and it starts just like nothing ever happened.Could this be the famous fusebox problem causing this kind of sympthoms?The prolem also appears when hot,after driving.I park the car,come back in about 10 minutes,try to start and wount start.When starting from cold no problems,always starts up properly.This is really annoying problem.Can anyone help?

ps.sorry about the language,hope you understand what I mean...

Problem solved!

It was the cps=crankshaft position/speed sensor.The heat coming from the sump caused the sensor to fail.It was ok when driving because the wind cooled it down.But when stopped and parked the heat made it fail=no spark.Actually it was quite easy to check.I just let the car idle so that it cut out.Then cooled the cps with compressed air and after that it started properly.I did the test couple of times just to make sure it was not just coincidence.

PS.try to help Yrkesman,he has a really weird thing going on on his cossie...
