Replaced fuel pump, filter. Had tank and injection system flushed. Still runs poorly. At the time of engine cutting out the gas gage will spike to full and the anti-lock brake light will come on.

Make sure your battery isin good shape and the connections are clean. Also make sure your main ground is clean on teh engine block. Check to see if there is a vacuum leak around your map sensor and have your engine scanned as you may have a problem. If you still don't get any codes then check yoru crank and cam sensors for ohms as they may be bad. If not a pro can do this.

The van is repaired. The shop found a broken wiring harness holder that allowed the harness to lay against the exhaust manifold. This caused a short in the crank position sensor.
