If anone has any ideas id appreciate them>?

2007 nissan frontier nismo 4x4

bought used from dealership in winnipeg not a nissan dealership

i live 6 plus hours away from nearest nissan dealership (one way) and last time i went to one they sent me home with a new battery truck ran fine... for a while!

i drive the truck every day

the truck will not start occasionally

 i dunno where to go from here pretty frustrated i got rid of an old unreliable vehicle for this truck paid like 20 thousand for this peice! i wanted a reliable truck but this frontier seems to have a mind of its own!!!

and live 45 mins from work i live in middle of knowhere not in the city so when i get stranded it sux. so new battery, new fuel pump, new fuel level sending unit

i have checked: every one of the small black supposedly non servicable non replaceable relays in the ipdm e/r  including ecu and ignition and starter relays they all check and work good when i check them with 12 volts and a multimeter.

I have not checked the bigger relays in the other box under the hood i cant figure out how to get them out they do appear to sorta have a loose slack fit.

first thought fuel pump was shot ....got it replaced

then thought maybe i had a bad relay or idpm board.... checked all relays they seem fine

then i thought somthing was draining down battery becuze after not starting the truck started right up with a boost. so i started disconnecting my neg. cable from battery when i would let vehicle sit. and after that it seemed to start every time........ up until today!! after work real cold minus 30 celsius it wouldnt start. also i talked to a tech on the phone and he thinks my draw in milliamps that i measured with the vehicle "off and asleep" was normal and would not drain down my battery unless i didnt drive truck for a reaaaaal long time like maybe months. So i got someone to give me a boost (like i said because that got me started last time this happened to me like a month ago before i started disconnect. battery term.) no luck. it turned over just as it did on its own without boost seems like a fast strong turn but will not fire up at all. then waited maybe 3 minutes 4 minutes and tryed again and a little spuuter and it started up but it was not a normal fire up.

99 percent of the time my trucks starts up and runs great but usually seems like everyonce in a while no pattern reelie just randow does seem maybe affetcted by sit time and temperature. but the one thing i have noticed is that it will never not start if i have just shut the truck off it mite be a coinsedence but i dont thi8nk so.   like after i got it going today and drove for 5 mins i shut it off and tryed to start it again and it started rite upno prob.     plz help anyone if u have similiar prob!
