My 280 has recently started to stall randomly and completely. Most of the time it will restart right away, other times, it requires a few minutes and/or an underhood visit without really doing anything but touching wires, etc. My guess is that this extra activity provides nothing more than more time for the car to sit.

On the last fill up I added two bottles of HEAT-type fuel system dryer and a 1/4 bottle of Castrol gas treatment/octane boost. Prior to that the only thing remotely close to this cutting out was some very brief cuts when cold, but nothing substantial enough to cause worry of a stall.

I've approached this from the aspect of a fuel probem so far, thinking that the additives have dislodged something that is plugging the fuel system momentarily.

After last night's ride home on a AAA flat bed, I layed in the driveway in the snow and removed the fuel pump. I removed the top and cleaned the screen and the reinstalled it. I removed the fuel feed to the carb and cleaned that screen.

I see no other fuel filter besides these two screens. I looked up the fuel filter on the Mann website and one is listed. Is that just missing from my car or was it not commonly installed or have I just failed to find it? There is nothing out back by the tank.

On the Mann website I found a reference to a part which looks like it is in the tank, a pickup with a screen, so I'll check that next.

I was also going to buy some sort of inline filter to add right before the fuel pump.

When the car stalls it is complete and sudden usually with no sputtering, save for a catch or two then total death.

I've noticed that the car seems to have some sort of electronic ignition module. This was not present on my parents' depated 1973 280 that I was familiar with in the past. Is this electronic ignition something that someone added along the way or was it an update for 1974?

Thanks in advance
