My 450 is randomly stalling??

In recent months, my 450 has stalled in different situations; I'll feel a slight hesitation in the power, then the engine just dies and the "check engine" light flickers on for a second or two. I can restart after a try or two (THANKFULLY!!! The last time this happened was in heavy traffic on the freeway WITH A SEMI BREATHING DOWN MY NECK!). It has stalled at freeway speed, while idling, in slow traffic with the AC on, so there seems to be no definitive reason for stalling.

Took it to my mechanic one, and he had no idea at all about it. (Sadly, I usually have to do all of the footwork when it comes to anything above regular A&B maintenance and parts acquisition...).

Any ideas? Similar experiences?
