Can someone please help me out here. My car just started to randomly stall whenever i drove it. Usually infrequently but some days it will stall multiple times within a 20 minute drive. I put in dry gas incase there was any water in the gas tank. I cleaned all of my contacts on the fuse box, and i changed the coil incase that was going bad, but nothng worked. If you have any ideas please let me know.

 

Its a 1977 911s targa by the way. 2.7 liters

 

Finally figured out what was going on. My permatune ingnition module was going bad which caused the engine to stall out. The module would stop giving spark to the engine usually when the engine was warm, or on hot days. I replaced the module with a new permatune and so far so good.
