Question about 1997 Jeep Grand Cherokee
I believe you have a electric fuel pump module (pump and sending unit is called the fuel pump module) that may be sticking (we call this a "lazy" pump) and causing this problem, in order to confirm that the fuel pump is the problem buy a can of spray starting fluid, and the next time it fails to start remove the air intake hose to the engine, spray in starting fluid and see if it fires off without holding the gas pedal down, the engine should fire up right away, and most probably stay running due to the fact the increased system voltage wakes up the lazy electric fuel pump, if that is the case you will need to replace the fuel pump.
Replacing the fuel pump module is shown with pictures at the web site below, I can't beat the pictures they are better than any manual diagrams..
