900S 2.0 NA stalls when warm !

Mistakenly, I posted this message on C900 Board, so now I am just posting it again here (the car in issue is actually 900 from '95).
SAAB 900 NA, yr.1995, with only 75.000 km stalls when worm and loose power under acceleration. Mechanics checked everything, replaced ISC valve and O2 sensor, but problem stays. Fuel pressure OK. When engine stalls it lights up Check engine with P0171 fault code (Mixture too lean). The engine stays without gas with no apparent reason, and it happens only when worm. Could it be faulty ECU or just pump relay or something like that. Fuel filter replaced, injectors cleaned, fuel pressure constant and in specs. Ignition OK, distributor OK.
It drives me nuts if I had to replace ECU. Could someone help? Thanks
