Shuddering Laser automatic

My daughter's 2001 Ford Laser auto has a recurring problem, which nobody can so far put their finger on. It only occurs, but it is quite distressing, especially when you are driving in traffic or stopped at the traffic lights. The engine shudders when stationary and feels like it's going to "conk out". It seems to correct itself for a time, but might come back a week or two later. Recently when I was driving it at 100 km/h the motor lost power and the speed dropped right back to about 80 km/h. After a few minutes the engine seemed to right itself and we continued on our journey without further incident. The mechanics we have taken it to have not been able to find anything wrong and nothing shows up on a diagnostic check.

Intermittent problems can be very hard to diagnose because they rarely happen when the mechanic is present. Same with the diagnostic checks, nothing will show up if the engine is running normally when the checks are done. I would be checking the various engine sensors, their connectors and the witting loom, looking for a corroded or poor connection.
