Stumbling and stalling
 
I have 74 911 with a 3.2 cis motor. Car starts and will run normally however when it gets hot it stumbles and stalls. Won’t restart until it cools. It will then restart and run until it gets hot again. Then it stumbles and stalls. Any thoughts on what’s going on would be appreciated.

Could be the coil. Check to see if you have spark when it is hot and not starting. Or borrow a spare coil to test.

Warm up regulator (WUR) . Got to measure pressures.

3.2 block with CIS? What year CIS?
What ignition system? CDI or ?
Need more information before making suggestions.

Do you have an O2 sensor? Points distributor?
