S10 Blaser Engine dies

It started out irregular but now quite often. When crossing over lanes, pulling out in traffic, real bad times. I checked it and it gave the code for TPS/ECM. I changed both, reset the TPS to 1.23v and it ran OK for a week then started again. It's exactly as if the key was turned off.
Sometimes it'll start up again while the car is still rolling, sometimes not. Sometimes I have to spin it over alot before it'll catch.
Ideas? The vehicle specs are in my signature line.

'86 S10 Blazer 4WD, '87 2.8 with 3.1 crank and pistons, A.R.I. "Stage 2 Cam", Iron Heads with stiffer springs, Holley TBI, Manifold bored to fit the TBI Base(4.3 size), Fiero Covers, MSD Coil, DynoMax Muffler and 2.5 Tailpipe, no cat, Auburn Limited Slip, 3.73 final Drive. 700R. '85 Fiero GT 3.4 Hybrid, relieved top intake and exhaust, 57mm TB, Auto. 3.06 final drive.

Checked the computer flashes and it said MAP sensor. Replaced with one I had laying around off a 3.4 and that appears to have solved the problem.
