Re: 3ltr will run OK then cut out (no warning) will start...
This problem is caused by a faulty thrust switch which is located on top of the intake manifold where the throttle linkage is located. It is a safety feature which, in case of collision, will kill the engine. This switch can short with age, and in the case of my 1989 300e, would kill the engine on left turns and approaches to a stop light. You can purchase a replacement at autohausaz.com, the part is located under "electrical" category, and itemized as "switch". The proper name is "thrust switch". It costs about $29.00 dollars and takes about ten minutes to replace.

It'll pay to have the crank sensor checked. They're known for heating up and stalling the car when they're no longer any good. Usually once it has cooled down the car will start but as soon as the sensor gets hot it'll stall again
Many cars have this feature. The fan will run for a few minutes at a time until the coolant in the radiator drops below a certain temperature. Most vehicles with this feature will have a warning label on the radiator shroud indicating that the fan may start without warning when the engine or radiator is still hot. The only time you would need to be concerned would be if the fan continues to run without turning itself off, and causing the battery to be drained.
check all vacume hoses for splits.this sounds also like air being drawn from the fuel tank sender unit which could be corroded.is there a strong smell of fuel inside the car?this could also be a secondary jet being blocked in the carb if it has one.good luck
Some cars cut off as a fail safe to overheating especially on newer cars. The computer controls the fans and if they are not working the computer is probably telling the car to shut off. Have you replaced the motors already, if not, this is what's happening. Once you replace the motors it should run fine. I wouldn't suggest driving it too much with this problem as it may affect the computer by giving it false info.
