Welcome to Allpar. Although not everything will leave behind a fault code, but are there any stored fault codes?
You want to jump in and check things (spark and fuel) when it is in start/stall mode. Check for spark at a coil pack. See if a shot of carb solvent will keep it running longer.
If you have or can borrow a scan tool, look at the sensor states when cranking. Make sure that cam and crank sensors are 'present', 'active' or 'in sync'.
An erratic security system or SKIM (gray body) key can also cause a start/stall.
Does it seem temperature related?
