86 951 randomly shutting off.

I went out to go to lunch on Friday and the car refused to start. It would crank and idle for just a second and die. I finally got it going and while running could here a huge air leak under the intake. I know if its bad enough a boost leak will cause weird cranking and running issues. Once it started I was able to crank it over and over and it was fine. After my shift ended I cranked it let it idle for about 10 minutes and drove it around in my parking lot. I get out on the road to go home and it dies and wont restart. I finally get it going again and make it back to my work and leave it in the parking lot over night. The next day I pull intake in parking lot and find a broken nipple on the cycling valve and find a few minor leaks at the AOS. I fix them all. The car cranks, idles smoothly and ran fine all evening. I drive it over the week end, everything fine. I head out for work this morning and the worst place possible it just shuts off. I jumper the dme relay and still no start but I can hear fuel running through the rail. I pull the jumper reinstall the dme relay and the thing cranks and I'm able to drive it back home. When I got the car it was non running and I have repaired the computer,bypassed alarm, installed a new injector harness, new dme relay, new timing belt, new tial waste gate, tie rod ends, replaced the oil pan, replaced the turbo and all kinds of other random bits and have daily driven the car pretty much since March with no problems until now. It had Lindsey chips,3.0 bar regulator, manual boost controller and tial waste gate for mods other than that the car is stock. Any ideas of what I can check?
