stalls when hot

I've got a 305 tpi. When the car is cold it starts right up and runs good. When it gets hot, say after driving for 15 mins, it will stall and sometimes won't start til it cools.

The tach would bounce around sometimes also. From reading others' posts I thought it would be either the ICM or the pickup coil. I replaced both along with the ingition coil and it got better, but the problem still remains. ANy suggestions on where to go from here? Thanks in advance.

Does the tach still jump around? If so, you still have an ign problem. If not, do a fuel press bleed-down test. You may have a leaking fuel inj/s.
