engines

Hi,i have a renault megane convertible 1.6 petrol 05 plate. my problem is intermittent engine stalling and hard to restart. the car will run sweet as a nut and then the revs die down and no matter how hard i try to accelerate it just wont steady up. once engine has stopped if i try to restart it it just wont refire, if i leave it for approx 10 mins it will run o.k till the next time it decides to play up (2-4 days)

has anybody had the same issues?

help please :confused::confused:
