That use to happen to me often but it was because the tps was not connected and my check engine light was on. I reconnected the tps and had my computer reflashed. It's been several weeks now with no problems.

With that MAF and TB I suppose you could be causing a lean condition... Do you have access to a wideband O2?

When was the last time the fuel filter was replaced?
