Default help 2wd cosworth not hot starting

does anybody know why a 2wd saph cossie will not start when hot?
if the car is left to cool down for 10-15 mins it starts back up, Ive just had a full engine rebuild with all new sensors etc apart from the ignition amp.
i have checked the plug gaps, phase sensor gap and crank sensor gap which seem to be spot on and the pump seems to be priming.
this is really doing my head in now so any info would be great

thanks.

Do you have spark on all plugs during hot start?

Could be a bit lean running check co when fully warmed up, then do the wiggle test whilst running.

Co would depend on whose chip it is(make), but around 2.5 in general, the wiggle test is just move/wiggle the wires with the engine running to see if it cuts out etc, helps identify any dodgy connections.
