Crank sensor, cam sensor, ignition module are the three things that usually cause this problem, the headache is catching them in failure mode to make sure that is the problem, you might check for any codes in the memory that might give you a place to start or if so inclined just replace them all at the same time, reset the computer and drive it as you normally do so the computer can reset it operational settings.

Not like a Cadillac, you need a code reader for this one.

I use a INNOVA 3160d. works on both my Caddie and my GMC Yukon.
