In hot weather u can b going down rd and 2003 chevy tahoe will die. Coast and will restart. Doesn't hardly do it in cold weather. Occasionally it will not restart and have to pull over on side of rd and wait few mins and then restart. Also if u floor it it will do nothing but coast then die. Thinking fuel pump but no clue really. Have changed fuel filter but didn't help. We hav had it placed on machine but it shows nothing

check fuel pressure with a gauge should be 60-66 psi if a small block or V6 if a 4.8-5.3L it will be a tad lower.
