Went to run an errand this evening and after 20ish minutes truck stalled. Waited about 30 seconds and would restart and run about 15 seconds and stall again had to do this several times to get home. In the middle of this I tried a different pmd and had no change. Temp outside is about 85 degrees. Diddn't have this problem this morning or after work. Only thing I have done is filled the tank. Fuel pressure is about 9psi at idle and 7-8 psi while driving. I haven't checked for air in fuel yet going to check that now. Any Ideas? Every thread I have seen that pertains to my problems never seems to have a report back on if the problem is fixed.
