Skoda Octavia starting problems

hello there good folk,

I have a skoda Octavia 2003 1.4 petrol,
and I'm having starting problems,

when I say starting problems its more like a restart problem. !

it starts every morning with no problem, the problem occurs its when I drive it for a bit, lets say 10 min to half hour drive,

then when I pop in to the shops or stop to get petrol, or I stall it at traffic lights, it won't restart, and have to leave it sitting for about 10mins! before I'm able to start it again, its very intermittent,

when the car is driving there doesn't seem to be any problems with it loss of power or chugging,
any help would be appreciated

thanks in advanced

😊
