I've had similar behaviour on my KLR650, just conks out at low revs for no good reason, after much thought and checking electrics and finding nothing wrong, I investigated a different avenue. I had a good look at the valve clearances and the decompression set up. Now the exhaust valve just under the decomp gear was just near the minimum clearance, but still within specs, so I did the valve clearances anyway and increased it to near the max gap. Also after careful inspection of the decomp mechanism, decided to stretch the retainer springs just a tad (very carefully), so that it didn't reset to quick at low revs. It seemed to cure the problem, can't say if it was one action or the other, but it might be worth a look at the mechanical side of things rather than the ecu. My Gen1 has had a reflash before I bought it I was told and I have never had a stall issue, it pulls away from low speed beautifully.
