03 savana shut off no codes 6.0 l

My o3 savana shut off with no codes, just dies. First run is the longest, then it gradually runs a shorter amount of time, until if finally won't start. If I continue trying once it won't start I can get a CKP code p0336. I've already replaced the CKP sensor. I unplugged the PCM at one point to check the connections, and after reconnecting I got the vehicle to run for about 4 hours before dying. Would only run about 20 min before. Any help is very greately appreciated.

Thanks is advance, Sam

Welcome to AF, my usual advice, the basics, do you have strong spark during the event and 60-65 psi fp?

Hi thanks for you quick reply. When the vehicle won't restart there is no spark. Fuel pressure stays at like 55 psi, until is dies, then it jumps up to about 62psi

also a strong smell of gas when it dies. and Thanks for the welcome to AF

Start looking for problems with the ign module or crank sensor for a no spark condition. Also have seen the coil secondary wire fail.

Any luck fixing the problem? i got the same p0335 code and already replace the distributor, ckp sensor, map sensor.. tried a MAF sensor and no luck.

This thread is a over a year old not much chance of a direct reply from the OP. What is the problem, no spark?
