1996 850 Turbo Stalled on the Freeway this Morning

Last Friday out of nowhere my 850 stalled when I tried to accelerate from a red light. After it stalled it took a couple tries but then it fired up again and got me home. However, the last week it's been driving weak, like there is a delay between putting my foot on the gas and acceleration.

Now this morning I was cruising down the freeway and when I gave it gas the car would not accelerate it just coasted, and then the rpms dropped and I was able to guide the car to the shoulder where the car then stalled and the dash lights all came on. I put the car in park, took a couple tries but then it started up again and ran fine and I was able to drive it home. I don't want to drive it again until I know what the issue is and fix it. The car always starts fine.

My first thought was that it is the fuel pump. I had some stalling issues last year at idle and replaced a likely original fuel filter that seemed to fix that problem but I wonder if it contributed to my pumps failure perhaps. The car has 146,000 miles on it. I preemptively replaced the fuel pump relay about 4 years ago. Any other possibilities I should look into? Perhaps the cam sensor? Thanks.

Sounds exactly like what my 850 did when I bought it. I tried to figure out where the issues was and was fixing some other issues along the way but not the main issue, running, driving and then dying out quickly. When I had it parked, I would have it running and pull the throttle cable, it would be a second long delay then idle up and stopped at around 5,000 rpm. I tried the fuel pump relay to no avail, tried the pump and it's bring working since then. I had the luxury of having a parts car so I didn't throw a ton of money into it. But because of that I was able to narrow it down with those symptoms and it didn't cost me anything. I would try the pump if the relay has been done already. Fuel filter could have caused the premature death of the pump easily from starving the pump or letting debris through.

I had an 850 that would stall randomly because the electrical cable to the starter that ran across the back side of the front subframe had worn completely through but made sporadic contact. If I were you, I'd trace the cable across the back of the subframe and make sure it is intact just to be on the safe side. I would never have been able to tell the cable was broken if I hadn't pulled and wiggled. Visually, the cable still appeared to be intact, but it wasn't. I think the cable was a ground, but I'm not certain.
