I recently purchased a 93 850 glt. great car , beautiful to drive. sometimes, out of no where, it stalls dead and all lights on dash appear. No code to warn the check engine light appears. I have had it stall while driving down the highway, while idling at a stand still, and when driving slow speeds in town. I've noticed other people with the same problem with the 850 and am wondering if anyone has found the fix. please respond with results or ideas on what to check. thanks.
