Long time reader on board but first time posting and hoping for some help.

I have 2003 Dodge Ram with 5.9 Cummins. 2 Weeks ago had water in fuel and it died so had it towed to shop where they removed the tank flushed out everything. Changed all filters, put in all new injectors and connector tubes. Truck ran absolutely fine until today, been through 4 tanks of fuel and about 4,800 km.

Today I went to work and it was fine, after work I had started it to let it warm up and went inside, came out and it was not running. But fired right back up. drove a few hundred feet down the road and it quit again and fired right back up and only made it a few feet and it would not restart for more than a second or two at a time. decided best to stop trying and get it towed back to my shop.

I usually do my own work but only had the above work done at a shop because I was way away from home.

Truck has 360,000 km on it, or 230,000 miles or so. almost all highway, never had any problems with it until recently. It has a Fass Fuel system, no chip or programmer.

Any help or suggestions anyone would have would be greatly appreciated.
