I unplugged the O2 sensor and the car ran worse than before, so I assume it's okay. Per co-worker's suggestion, I removed the gas cap. He figured from my syptoms either gas cap or fuel pump. The car ran for the first time in a while without the same problem recurring. It started great, ran good up to 80 mph. No problem accelerating. I drove several miles with no problem. Stopped at store and when returned, it died three times in idle, but again ran great once I got up to speed. I've added fuel injector cleaner (cheap stuff) several times in the past, but this could be part of the problem. I'll try some good stuff. Not quite ready to trust it yet. I figure if not fixed, I'll check fuel pressure next, then back to sensors. I'll reply when fixed. Thanks for the input.

The relay is the ignition relay. The original (for 93 Legacy L AWD) is manufactured by JIDECO, part # 25229 AA001. Also has numbers RELAY 2M / MR5A414A1K12V / 20702M on it. Advance Auto carries this as GP Sorensen #41-5005 for only $15. HOWEVER, I just replaced mine today and no luck. Thus far, I have replaced the fuel filter, coil, plugs, wires, air filter, pcv valve, cleaned battery posts and connectors and now this ignition relay. Still no luck. Tank is about 3/4 full right now. I added some HEET, just in case moisture had accumulated. No luck there either. I'm thinking the O2 sensor is my next shot. Mine starts fine, runs good initially, gives you that warm fuzzy and then as you reach about 50 to 60 mph, it suddenly just lopes, pedal to the floor and she continues to drag, let off gas to pull over and she dies. Starts back up rough, idle drops very low, but works good enough to get back home as long as I keep the speed < 50 or so. I'll follow up when / if I fix it. Good luck.

I have a 93 with the exact same problem. It happened ~ 10 times over the past year. Suddenly the car won't accelerate, you push the pedal to the floor, still no accelleration, let off pedal and the car immediately dies. Pull over, remove key, wait a minute or so and it's fine for another month. However, now it's happening constantly. I can't get a 1/2 mile prior to it stalling on me. Plus now it doesn't recover quickly, it tries to cut off every time you hit the clutch (rpm to near 0). This thread of messages never ended up with a solution. Did anyone resolve the problem? How? I replace the coil, plugs and wires. I'd hate to waste any more money on the wrong fix. Can the O2 sensor cause the car to cutoff? I was thinking of replacing the ignition relay or O2 sensor next.
