97 250HD bad starting issues

[97powerstroke87]

My 97 powerstroke has issues starting. It runs descent once its running although it has a hiccup one in a while at idle and sluggish at times. It has a newly rebuilt computer new cam sensor and new fuel filter. Somedays it will sputter for a split second and crank over fine. Other days it will sputter a lot and then start, sputter and start and then shake like crazy to the point where you have to shut it off immediately and wait like 30 sec and then it will start and run fine. recently its been gettin worse where it will crank and crank and do nothing finally start sputtering and then if you keep cycling the key on and off waiting inbetween it will start up and run. It is also draining down my battery. Any insight? i here of the idm or ipr but im not sure whats going on.
