Might try putting the old cam sensor back in to see if that changes anything. The crank sensor is usually the culprit for engine cut outs and bucking. 97 and up the cam sensor primary function is to set timing info at start up. After that it's only used as a comparator to the crank sensor for fault status. Distributor on a 3.3 ????
There is an inspection plate on the bottom of the bell housing on a 4 speed 41TE tranny. Sometimes a cracked flex plate can be detected there or by removing the starter. Unfortunately, there are times when it can only be detected by removing the tranny to get a good look.
Got a hunch you know this but just in case the ring gear on the flex plate is what the crank sensor senses to generate it's timing signal. If the plate is cracked and sometimes the bolts sheer, the plate "wobbles" creating erratic sensor data. You see it as hard starting, bucking, stalling.
