Hi! This is Bo with Car Genius at RepairPal! 228,987!?!?! That's awesome! In my research, I came across a very similar situation. The tech found the crankshaft position sensor was intermittently failing. Here's what they said: "Stalling when cold.Ok when warmed up.67000 miles. No Codes. Checked crank position sensor for zero to five volt square wave with lab scope. Waveform would shorten to two to five volts when acting up. Replaced crank position sensor and timing belts also while covers off." You could try having it diagnosed with this in mind before throwing a part at it just in case!
