Car won't start after driving short distances i.e. to work, groceries etc.....all are a 10 min drive. We just had a 700 dollar service done last month 10/01/10. Thoughts anyone?

the coolant temperature sensor is the better bet as to a problem sensor
however having the fault codes read at a professional service centre will save lots of money and time

Engine stops running or transmission stops pulling ?

Replace the fuel filter first. This will take pressure of the fuel pump, make it pump more efficient. Catalytic converters will also cause this kind of problem.

Have you looked into your crankshaft sensor

CHECK MODULE

Your only choice is to take it to a trannmission shop to have it diagnose,

When it will not crank, a mechanic would check for voltage at the starter, the clutch safety switch, and the key switch.

check your ground wires

I have a 1995 Dodge Stratus and I had the same problems last winter it turned out to be the main brain the ECU as they call it It costas about 1200 dollars new but i scored mine from a junk yard for 10 bucks and my car hasnt done it since. They very well may be your problem because i have the same engine in my car its just a smaller body style. look on the net for spaldings used car parts u can look up parts and they usually sell ecus for 75 to a 100 dollars.

The first thing I would check with the limited information that you gave, is to have the fuel filter changed if you haven't done so. We need more information to diagnose other problems, including engine size, etc. Hope this helps you, Rick
