My 1987 CHRYSLER LEBARON GTS 2.2L 135cid L4 TBI (D) automatic 4door hatchback has a tendency to stall unexpectedly. It will do this any time, anywhere, at any temperature (cool or hot). This problem is intermittant, with days or a week or more between incidents. Typically the car starts fine and drives fine for at least 3 miles before stalling. It can stall at any speed, from idle to highway speed (it has stopped cold on the interstate). Typically, it will then refuse to restart for at least 20-30 minutes before restarting and again appear to run fine.

I have checked the electrical connections and vacum lines for breaks.

The cap, rotor, spark plug wires, plugs, air & fuel filter, look good.

I checked the engine codes via the instrument cluster "check engine" light method and it showed no problems.

I suspect a fuel problem, but can't be sure. The most recent service work was to replace the rusted and leaking gas tank, reusing the old fuel pump and sender assemblies. But this was several months ago and the car had run fine (for awhile).

I had heard this problem was typical of MAP sensor failure so I replaced it with no affect.

Does anyone know a cause of this problem that might be specific to this vehicle?
