I took My Van In To Be Serviced to See Why It Wouldn't Start, I Was Told It Might Be The Fuel Filter, Then I was Told It Might Be The Water Pump, Then I was Told It Might Be An Electrical Problem. I Have No Clue What It May Be Please Someone Tell Me What It Is

This acting up of what I think is a bad ground has not happened in two months.
Yesterday, 6 times in less than 60 miles. Recovery time may be coast to stop turn off ignition switch and then start up or coast to stop no start then wait 35 min than it will start.

Prior to problem, I missed noticing interior courtesy light was on. (In exiting, I sometimes brush to overhead light and it turns on easily) Not using the van for a couple of days, allowed the light to discharge the battery. After re-charging the battery, I started the van engine, quite easily - as is the norm'... engine accelerated normally in-place but engine immediately stops when foot is lifted off the gas pedal! The engine re-starts with the same after effect.
No diagnostic codes visible

When idealing sometimes it will stall and sometimes it wont.

power, and overheating. Oh and it started squealing too. And the generator warning light came on.

When the switchpasses thru AC, it blows the fuse, thus vehicle will not start, and no cold air also before fuse blows.

i feel a jump or surge in the truck at aproximately 45mph sometimes even cutting out. this happens all the time no matter the difference in ambient tempeture. Is anyone familiar with this problem?

My daughter drove the truck home turned it off went to crank it up a couple of hours later and it wont do anything but turn over. We have replaced the crankshaft sensor and fuel filter. Cannot figure out what tells the fuel injector to engage... Help anyone, Oh Yeah its a diesel..
