I would suggest checking the fire at the plug with a phillips head screw driver, remove a plug wire and insert screwdriver in plug boot, hold the handle as to not become the ground yourself, place shank of screwdriver close to metal part on block and crank over engine, see if you've got spark. Note color of spark, blue to white strong ignition, yellow weak, no spark you've pin pointed the problem. Remove gas line from pump to carb, turn key to on if electric pump, do you have gas? If mech pump bump over engine is there gas? If not then back up and remove line from filter repeat test, on gas then maybe its time to replace filter. There is a filter on the outlet line in the gas tank, non-replaceable, you can try and unclog it with a small tire inflation pump I'd recommend a 12 volt, be careful of spillage with the gas while your checking the fuel system, don't want a fire.I had this stalling happen several times before I discovered the filter in the tank was blocking the fuel to the pump, I got lucky the airstation blew the entire filter off in the tank and its to big to block the line again.I had replaced everything in the dist. before I checked the fuel, I thought it was a condensor or coil heating up and failing. If you check the plugs by looking at them don't be alarmed if the plug is pretty black at the tip, thats sort of a normal condition for the a-4.
