yes, old wires and old connections.
one thing about wiring, and electrics, once intermittent? they almost always get worse. and when that happens, it's easy to find the cause.
no spark, no fuel. paths.
if it comes back, drive with the diag jumper inserted
12,12,12, etc.
some other number?
dead?
the lamp must flash even at stall. (if not, the ECU is bad.) ever replace the ECU caps yet, they dont last 20 years. not even close.
watch the cel, lamp when it dies. what does it do.
we are working a problem that we think the engine is good. (good compressing and runs hot or cold, only bumps mess it up) so engine is good.
spark you thing its good, have you ever checked the Dizzy VR gap? this dizzy makes all all spark and are notorious for very odd failures. Ignitor, etc. inside.
so we presume the problem is just bad injection.
1: lost 12v power to eCU (ground is part of that)
2: bad inputs to ECU.
3: bad ECU.
4: injector bad ,flaky or loss off fuel pressure.
what makes this very hard, is the lack of a scan tool, that would in fact discount 1,2,3 errors, above. or even reveal the bad input.
on the other hand what input to ecu cause stalls. (not correctable by a fast right foot , a true stall)
THE ECU on this car is FUEL injection ONLY ecu, the ECu does not create or time spark, like 91+_
in no order.
A: lost 12v power. any thing related to MAIN relay. even a loose IG coil fuse or wiring hacks to same. this fuse bad (corroded) kills spark too, main powers the ECU and the fuel pump.
B: CODE 41s.
C: Bad ECU. (all 90-95 fail for caps 1 time. are yours caps fresh?)
D: MAP goes to 0v. dead. for any of 3 or more reasons.
E: bad injector wires. (or injector, or
F: bad wires from ECU to both Main relay coils. or any wire to main, or connector to main or heck main relay bad it self $$$$$
