Hey guys, I've got a 2004 titan with 152k on it. The other day the engine randomly died as I pulled into a parking spot. Tried to start and it would just crank, 3rd time I cranked it she fired up. Made it all the way home (20 min drive) and as I pulled in the driveway it died again. This time I couldn't get it to start again, it would just crank. Went to search on the forums and found out about the ecu relay issue. Picked one up the next morning from the dealership and put it in, then it would start but very roughly and it would stall out every time I attempted to put it in gear. Went and rented an OBDii sensor, and it threw a p0335 and a p1051. Went to autozone real quick and grabbed a CPS and put it in. Still doing the same thing. I actually got it in gear yesterday by feathering the gas as I put it in drive. Drove it around the block and the first stop sign I hit it died, finally got it started back up and then it died as I pulled into the driveway. When it's in park or neutral it will idle just fine and you can rev up the rpm's just fine, but when in it's in drive it dies. Any ideas on what could be the issue?? I thought for sure it was the ECU relay or the crankshaft position sensor so now I'm stumped.
Rough starting and stalling at stops

P0335 could also indicate a problem with the IPDM, bad grounds, or low voltage, assuming the crank position sensor is OK. Search for threads regarding the IPDM issues. Clean grounds, and make sure your battery voltage and connections are good.
P1051 is a low voltage signal from the bank 2 A/F sensor 1 (forward O2 sensor), so I'm betting on a voltage-related issue. Cam position sensor is the other possible culprit with your symptoms, I believe. Diagnostic flows are in the Service manual.
Hope that helps.

Thank you for the advice! I will check the grounds and connections in the morning. I'll check the voltage on the battery too, but it's only 2.5 years old so I wouldn't think that's it. I too was also thinking maybe a cam sensor, so I guess if I can't get anything figured out that will be my next step.

You bet.
I've seen less than year old batteries from some auto parts stores die. Always a good starting point on these trucks, which are very sensitive to having good grounds and proper voltage.
Before throwing parts at it, suggest looking in the Service Manual for the diagnostic flow. It will walk you through some of the voltage checks, other items, etc.
Good luck!

Update so far... Went ahead and recharged the battery and checked all the grounds, everything seems to be order. Followed the diagnostic flow charts on the crankshaft position sensor. It looks like the sensor and the harness are getting the correct amount of voltage. The camshaft sensor was giving some weird intermittent numbers though so we went ahead and swapped it out. It actually started up after a little bit of cranking on the first try. Sounded much better and I thought we might be in business, but it still died when I put it into drive. Any other ideas?? I also did the manual ecu reset and it's still throwing the p0335 crankshaft position sensor code.

Would be checking fuel pressure
Going to try to get ahold of one in the next few days. Thanks for your input!
Finally got the truck up and running again. The crankshaft position sensor I put it was no good. Put a new one in and it fired right up lol. Not before I accidentally broke off the overflow nipple on the radiator though unfortunately. Drilled out the hole, tapped it, and put it in a brass fitting. Globbed on the RTV around it and so far so good.
