Electrical problem
2000 Daewoo Matiz 4 cyl Front Wheel Drive Manual 126000 miles

Dear Sir,

I have a problem with my car, when i start it starts well and stops after 5 min, i changed plugs, leads and checked fuel pump i can see fuel in return pipe when i put the key on, but still it is like that, before stopping there will not be any engine computer alarm, if i try to start again immediately it doest start, if i waite for around 2 hours or more then starts and stops again.

Please suggest me what could go wrong

Thanks and Regards
