If you have a code for a sensor and a new one doesn't solve the problem, you'll have to measure the voltages on its wires when the problem is acting up. When the engine stalls, do not turn the ignition switch off and back on. Leave it on, pop the hood, and measure the voltages on the three wires. One must have 5.0 volts and the ground must have around 0.2 volts. If there's no 5.0 volts, check if it's present at the camshaft position sensor. If it is, there's a break in the feed wire to the crank sensor. If it's missing at both sensors, the Engine Computer shut that power supply down to protect it. Try a new cam sensor or look for a place where that wire is rubbed through and grounding out. When the short is gone, turning the ignition switch off and back on will reset the 5.0 volt power supply.
If you find 5.0 volts on all three wires, the ground wire is open. Measuring the voltages on the cam sensor again will tell you which part of the wiring the break is in.
