1995 mitsubishi eclipes turns off without warning while driving?

Does it idle rough ? Black smoke coming out of tail pipe ? Cranks easy or long ?

Have you had it hooked up to a scan tool ? check sensor data ! Your vehicle has no cold start valve . Black smoke out the back indicates a rich condition , holding gas pedal to the floor causes the engine computer to go into WOT mode shutting off the injectors . Suggest you do injector leak down test , leaking fuel injectors ! Ever replace fuel injectors ?

Check crank shaft sensor.

The engine is not designed to run without the turbo. Fuel pump recirculates fuel to the tank to control pressure while driving and engine is running so poorly fuel is being diluted. Fix the turbo.

Should be on or near the fuel injector supply rail.

Driving around for a couple days- is one thing

Not caring at all & driving for weeks with a check light
on,hope for the best & no damage or at least something
you can afford

Low oil level by a few quarts,really,how's that possible?

A bad crank sensor will shut the jeep off suddenly, while driving down the road, then restart later and it repeats over and over until you replace it.

Had similar problem with 97 Plymouth Neon.  It turn out that the Crank Shaft Position Sensor was failing,  since I replaced it the car has been running smooth with no problems.
