1996 Ford Laser out of solutions?

I have a 1996 ford laser K, J, 2. (1.6 twin cam) runs great when cold after 5 min power dies, rev counter drops to 0 lights on dash come on. Engine will crank over but not fire.
1.I have change the dizzy (no change)
2. Took to local auto elecy they had for one week results that come back are as follows:
. Checked wiring on ignition switch
. Check starting
. Extract codes 03 dizzy-08 air sensor
. Check wiring between dizzy and ECU
. No pulse to ECU
Diagnoses needs new dizzy.
So I bought a 3rd dizzy and installed still same as: runs for 5 min cut out but this time fuel pump stoped as well and no spark gave it a rest and she fired up again.
any solutions I am stumped?
