so I pick up this cirrus drove fine first day . Next day in the morning I turned it on . About a minute went by and it shut it self off . Thought maybe it sat awhile before I bought it . So drove it to work and with in 25 minutes came to a light and it shut off at the light .started right up . Still doing the same thing . Replaced the alternator because it failed voltage regulator. Swapped the auto shut off relay . Cleaned the throttle body and cleaned the iac . No change . No codes no lights on dash . Any ideas ?

These readings are bogus. The TPS voltage is about 0.7 volts at idle, increasing linearly to about 4.0 volts at wide open throttle.
Oops that’s .77 rest . .85 at idle . And when wot it’s 3.75
So, a final test would be to read the voltage while sweeping the throttle through its range (with key on, engine off). If there are no unusual spikes along the way, the TPS is good.
