Could a failing O2/ MAP/ water temp/ throttle sensor on my E6a cause a random crippling loss of power occasionally followed by an explosion in the pipes while driving and random sputtering and wanting to die at idle? Help...

So today I got my stalling problem narrowed down to something electrical. Come to find out when it has the loss of power and stalling, there is simply no trigger signal at the ignition unit... SO I'm going to start with putting in a different crank angle sensor, then I want to test out the magnetic signal stabilizers that are between the crank sensor and the haltech (does anyone know how to do this?) and if that dosent work then I'll have to look at the signal coming from the haltech to the ignition box (anyone?). As of today, the car will start, idle fine for 5 or 10 seconds, then die. Repeating the process gives identical results. At least yesterday it would make it to the end of the street first... Do crank angle sensors go bad? What electrically would cause it to run fine one moment then repeatedly misfire the next? Any other advice for me? All my friends are lauging at me but they know deep down that when I get it running good I'll be invincible... hehe ~ Jeremy

Ok today I tried a known working coil and also a different crank angle sensor. Negatory on both. My next step is to somehow see if the magnetic signal stabilizers are bad then after that the (gasp) haltech itself. The car will start and idle for 3 to 5 seconds then die exactly as if you turned the car off with the key. The trigger signal just stops. You can see the light flashing on the MSD ignition unit for each trigger signal it receives. Keep in mind the problem started as a misfire when I was hauling ***, then progressed to stalling after misfiring when I was just driving, then to this. It seems like I turn it on, the haltech takes a look around, then sees something it dosent like and kills it. Possible? Anyone?

I just did datalogs yesterday, and I noticed two odd things. (I don't have the manual for the E6a yet but I did order it..) First next to the MAP values there is an asterisk when the car is running. Second at no time while running did the voltage in the system go above 11.8v. My battery dosent seem to hold a charge above 11v (optima) and I also tried with a known good battery (12.9v) so maybe the alternator is dust. If anyone wants to take a look at my datalogs I'd appreciate it, my email is jeremy@ferberphotography.com

It RUNS!!! it was a damn circuit breaker.... Thanks guys
