My 1987 260E stumbles and stalls after it gets to temperature. This only occurs after it sits over the weekend. I have changed the fuel filter, OVP, voltage while running is 13.68 on the batter terminals. Seems like this might be related to a sensor problem. Seems like the battery is running low on voltage or something. The alternator was checked at my local parts store and they said it is good. I am stumped and so is my local garage.

Thanks, Bob.
