1994 Laser

[steve666]

i have a 1994 Ford Laser Liata LXi KJ which i under stand has been fitted with a Mazda 323 engine from ford. the problem is the engine starts and runs well.

Problem is i can drive fore a short period of time (5-10) minutes and the engine just cuts out,stops dead.If i wait for about 10 mins (sometimes longer) the engine will start and i can drive again, and it will stop again.

I have had all wiring checked and could find no fault.

I have replaced the fuel filter in engine bay. replaced the coil packs and spark plugs. it does not seem to have a vacuum leak. also checked electrical connections for bad contacts and all in the engine bay were ok. the only thing that i have noticed is that the electric cooling fan for the radiator starts up when i start the engine.it does not seem to make a difference whether the fuel tank is full or low. I am at a loss as what to try next.
