If you worried about your gas, put in a bottle of sta-bil or ISOheat. This will remove all water and condensation from the gas. I would also replace your fuel filter, spark plugs and WIRES. Check for any vacuum hose leaks, if needed do compression test to verify that your gaskets aren't leaking.
If you have service/check engine light on, have a diagnostic test done to pinpoint the bad sensor or circuit that is setting it off.
Hi, I had simmilar problem with my 1993 JGC . I ran out of gas and it would not start until the next day. Then it will start and run until I put the brakes on tho stop and then it will die. It starts right back up. Ended up being the voltage regulator in the ECC/ECM. It is at the mechanics shop right now waiting for the ECC to come in.I will post a follow up.
Could be a sensor.I'm thinking more along the lines of a fuel pump or fuel filter.If the fuel pump is going bad..similar symptoms.Would be advisable to install a pressure gauge at the engine,and check fuel pressure when it's acting up.
